Molded Case Circuit Breaker (MCCB)
Molded Case Circuit Breaker, MCCB, is an electrical protection device to protect electrical circuits from damage by overcurrent. Prevents overload, short circuits, and switching of circuits. About ComPact Molded Case Circuit Breakers, MCCB. Protect cables sized for 100A to 3200 A. They now come in various sizes, intelligent metering, and monitoring, and with integrated earth leakage protection. Their highest breaking capacities allow them to protect also smaller cables when connected close to a powerful energy source.
MCCB uses a temperature-sensitive device, also known as a temperature element, with a current-sensitive electromagnetic device, also known as a magnetic element, to provide the trip mechanism for protection and isolation purposes. With this, it can ensure overload protection, prevent short circuits, and act as an electrical disconnector switch.
