Custom Solutions For Power Distribution
Cooper Bussmann plays a key role in developing custom solutions for vehicle power distribution applications.
Once a product need is identified, an innovative team of design engineers works closely with the customer to
discuss their needs. This enables our team to design and develop custom solutions tailored to meet specific
customer requirements.
Many custom solutions include developing linkage systems to join two or more of our products together. This
allows the customer “one-stop shopping” to create their vehicle electrical system. Other examples include
bussing/jumpering, color-coding, and changing thread sizes.
If you are in need of a custom solution, please contact your Bussmann sales representative for assistance.

Bussmann®
SERIES 31000/32000 VEHICLE ELECTRICAL CENTERS
Cooper Bussmann’s Single Vehicle Electrical Center
(VEC) and Dual Vehicle Electrical Center (DVEC) are
widely used Transportation Industry power distribution
modules. The VEC & DVEC use patented programmable
3D matrix technologies that can be easily modified to
accommodate changes to an electrical system. These can
be customized for each specific electrical system, but
require no tooling for implementation.
VEHICLE ELECTRICAL CENTERS
The VEC & DVEC accept automotive components including fuses, relays, circuit breakers, diodes, and other
devices that have 2.8mm wide terminals on 8.1mm centerline spacing. (See page 5 for additional available components.) The compact size of the VEC (about 4”x4”) and
larger size of the DVEC (approximately 8”x4”) provide for
high component density. VEC’s provide either 8.0mm
bladed inputs or M8/M6 stud inputs. The VEC can accommodate up to 2 input connectors - 4 bladed inputs or 2
studs - and 4 output connectors. The DVEC can accommodate up to twice this amount. (Some designs may limit the
number of connectors available for use.)
BENEFITS
The customizable designs of the VEC/DVEC enable them
to incorporate many different devices and multiple design
variations. Splices in the harness can also be eliminated by
internally programming them into the grid matrix. The
inputs (connector or stud) and outputs (connector) of the
VEC/DVEC are color-coded and keyed, and provide quick
installation. This makes the module easy to service. The
largest benefit of these modules are the reduced lead
times and zero tooling cost.

Basic Overcurrent Technology
Overcurrent devices may serve several purposes in
electrical circuits:
• To protect components, equipment, and associated wiring
from the effects of electric circuit overloads and/or short
circuits.
• To isolate branch circuits from the main power supply
once an overload or short circuit has occurred.
Fuses and circuit breakers are commonly selected as the
preferred overcurrent device.
TYPES OF OVERCURRENT
An overcurrent device is constructed to react in a
prescribed fashion to varying levels of electrical current,
where at pre-determined levels, the device provides
interruption of the current flow through it. Any current that
exceeds the ampere rating of the fuse or circuit breaker is
an overcurrent. Overcurrents are generally classified as
either short circuits or overloads and are defined as
follows:
• Short circuit - a current that greatly exceeds the rating of
the device. It is caused when a malfunction or accident
creates a break in the normal path allowing electricity to
flow directly to ground or another phase. This shorter
current path bypasses the resistance offered by the
circuit components and the load connected in the normal
current path. In this situation there is little resistance to
impede the current and the current will build to a level
where the heat generated can cause insulation damage
and/or equipment breakdown.
CIRCUIT PROTECTION PRODUCTS
18
• Overload - an overcurrent that is within the normal
current path. Overloads occur when the current exceeds
the value for which the equipment or associated wiring is
rated. This typically occurs when too many devices are
connected to the circuit or when a device connected to
the circuit malfunctions. Overloads are also caused by
harmless temporary surge currents; such as when motors
are started. These overload currents are normal, usually
brief in duration, and have no harmful effect on the circuit
components. (It is important that protective devices do
not react to such overloads.) Sustained overloads,
however, may slowly cause overheating of the wiring and
the components. Provided the overload is of sufficient
magnitude and duration to activate the device, the circuit
protection device shall open before the overload induces
system component failures.
SELECTING OVERCURRENT PROTECTION
During normal conditions, an overcurrent protection device
must carry the current without nuisance openings.
However, when an overload or short circuit occurs the
device interrupts the overcurrent and withstands the
voltage across the device. To properly select an
overcurrent device the following items must be carefully
considered:
• Voltage rating - represents the maximum system voltage
present in the circuit in which the overcurrent device is
installed. The system voltage should not exceed this
value for proper operation of the device during an
overcurrent event.
• Current Rating - the amperage value marked on the
circuit protection device. The circuit protection device is
designed to handle this value under steady operating
conditions and at room ambient temperatures. Since field
applications often deliver loading conditions and ambient
temperatures that vary from ideal nominal settings, it is
recommended that circuit designers select device ratings
above the nominal circuit current continuous load to
prevent nuisance trips. Additionally, the continuous
current flowing through the overcurrent protective device
should not be more than 80% of the current rating.
• Characteristics of equipment to be protected - during
the operation of protected equipment, system current can
significantly vary. This is particularly evident when motor
or other inductive loads in the circuit cause large current
surges during start-up. Circuit protection designers should
be aware of these surges and/or in-rush characteristics
and select the overcurrent protection devices accordingly.
• Available short circuit current - during a fault or short
circuit condition the fuse or circuit breaker may see a
large amount of current. Large DC battery supplies and
high current rated electric distribution buses often have
this potential for severe short circuits. In these situations,
the circuit protection device should have an interrupting
rating that is equal to or greater than the short circuit
current that can be delivered.
• Ambient temperature - the time it takes to interrupt the
current is dependent upon the ambient current
temperature characteristics. Ambient temperature refers
to the temperature of the air immediately surrounding the
circuit protection device. The ambient temperature around
the fuse or circuit breaker can be appreciably different
than the outside room or larger enclosure containing the
device. This can occur when the device is contained in a
tight area or it is mounted in or near a heat-producing
component such as a transformer or resistor. When
selecting a fuse or circuit breaker at ambient
temperatures significantly different from the stated
nominal temperature, the circuit designer should adjust
the selected overcurrent protection rating based on the
published temperature re-rating curves.
OVERCURRENT PROTECTION DEVICES
Two categories of overcurrent devices are available.
Fuses
The key component of a fuse is the “element’, a short
piece of metallic wire or link made of a material with a
Cooper Bussmann Transportation Products • Phone: 1-888-867-8194 • Website: http://www.coopertp.com
relatively low and predictable melting point. Fuses are
current-sensitive devices and the resistance is so low that
they simply act as a conductor. Circuit protection is
provided when the fuse element melts and interrupts an
overcurrent. The key criteria used to judge the performance
of a fuse is the time-versus-current characteristic curve.
This curve can be used to match the fuse with the load.
Fuses may be preferred when fast response to a short
circuit condition is required or when high available short
circuit currents occur. Fuse characteristic curves can be
used to carefully size the device to a critical or special
application.
Thermal Circuit Breakers
The basic components of a thermal circuit breaker are the
thermal alloy element, electrical contacts, and the terminals
for external connections. When an overload occurs, heat is
generated as the current flows through the thermal alloy
element causing it to deflect and separate the electrical
contacts, interrupting current flow. An important parameter
used to judge the performance of a thermal circuit breaker
is the time-versus-current characteristic curve, which is
similar to that of a fuse. A thermal circuit breaker is
generally not a one-event type device as is a fuse. The
resettable features of circuit breakers are often found
attractive for use in electrical circuits where non-resetting
interruption of current flow is undesirable. It is important to
note that cycle life of a thermal circuit breaker is
impacted both by the operational characteristic of the
circuit breaker as well as the relative magnitude and
duration of overcurrents or short circuits that the
device experiences. There are different operational
characteristics of Cooper Bussmann thermal circuit
breakers, which are described below.
CIRCUIT BREAKER
OPERATIONAL CHARACTERISTICS
• Type I (automatic reset): the circuit breaker trips and
resets in response to the overcurrent condition in a
repetitive fashion. This version should be used in
applications that provide for other self-limiting or
non-resettable means (such as after a main fuse, main
manual-reset circuit breaker, or momentary switch).
These devices, while automatic in reset function, are
not designed for long-term cycling conditions in
applications where operator awareness of circuit fault
or serviceability access is limited, leading to
unsatisfactory failure events. Refer to SAE J553 or
J1625 for additional details.
• Type II (modified reset): the circuit breaker contains an
additional resistive component that enables the device to
have only brief trip and reset activity and then afterwards
maintains an open circuit condition (except for a low
• Type III (manual reset): the circuit breaker will trip in
response to an overcurrent condition after which a reset
button or lever extends externally to indicate that the
breaker has tripped and is in a non-conducting state. The
trip indicator button or lever must be manually activated to
return the device to normal operation.
• Type III (switchable): same as the manual Type III
manual reset with the additional feature of allowing the
user to open the circuit using an externally accessible trip
mechanism.
CIRCUIT BREAKER APPLICATION NOTES
• Circuit Breaker Performance - Cooper Bussmann
thermal circuit breakers are designed to conform to
relevant industry standards (refer to individual models for
standard references). There are specific performance
aspects that may not always make circuit breakers
suitable for certain applications, especially in circuits
that are incapable of providing enough current to
operate the circuit breaker in a timely manner relative
to the associated components and wiring. It is of
utmost importance that the circuit designer investigates
components that have finite overload capabilities which
are below the time-current levels to initiate timely circuit
breaker activation.
• Evaluation - Design-in situations require that the user
considers all application conditions and conducts
operational testing to establish the correctness of
ampere/voltage rating as well as overload protection
suitability. Further review of industry standards is advised
to understand all performance aspects that affect usage.
• Wiring Considerations - Additional evaluation of circuit
conditions is essential to achieve proper matching of wire
sizes to the current load conditions anticipated under
normal operating conditions, and estimated abnormal
operating conditions when overloads could occur. Thermal
circuit breakers and fuses introduce some level of
resistance to the current path where installed. These
factors should also be considered when choosing wire,
both in gauge as well as in temperature rating
of insulation.
• Installation Environment - Thermal circuit breakers are
produced in various configurations. Installation
environmental conditions need to be considered and
compared to the capability of the particular product of
choice. Not all circuit breaker designs are suitable for
harsh conditions, such as may be encountered underhood or external cavities.
