Different Types And Sizes
• Molded Case Circuit Breaker (MCCB)
“A circuit breaker that is assembled as an integral unit in a supporting and
enclosing housing of insulating material.”
• Insulated Case Circuit Breaker (ICCB)
“A circuit breaker that is assembled as an integral unit in a supporting and enclosing housing
of insulating material and with a stored energy mechanism.”
• Low Voltage Power Circuit Breaker (LVPCB)
“A mechanical switching device, capable of making, carrying, and breaking currents under
normal circuit conditions and making and carrying for a specified time and breaking currents
under specified abnormal circuit conditions such as those of short circuit. Rated 1000 V ac or
below, or 300 V dc and below, but not including molded-case circuit breakers.”
