Molded Case Circuit Breakers - MCCBs

What are MCCBs? Molded Case Circuit Breaker, MCCB, is an electrical protection device to protect electrical circuits from damage by overcurrent. Prevents overload, short circuit and switching of circuits. About ComPact Molded Case Circuit Breakers, MCCB. Protect cables sized for 100A to 3200 A. They now comes with 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. As one pillar of digitally connected power distributions (EcoStruxure Power), ComPact breakers take part in energy consumption and asset management optimization. Benefit from 65 years of technological leadership, and rely on proven quality, opted for even in most demanding environments. How does MCCBs work? MCCB uses a temperature sensitive device, also known as temperature element, with a current sensitive electromagnetic device, also known as magnetic element, to provide the trip mechanism for protection and isolation purposes. With this, it can ensure overload protection, prevent short circuit and act as an electrical disconnector switch.
