That flat thermal curve simplifies panel design: you don't have to oversize for a warm enclosure. The 3-pole unit delivers 187 kA breaking capacity at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V.
Line protection design with communication and shunt trip
This MCCB is configured for line protection — the primary role is feeder and main distribution protection in a panel. It carries a communication function (enabling integration with a BMS or plant SCADA) and a shunt trip (STL) for remote emergency-off or automated load shedding. Two HQ auxiliary switches provide status feedback to the PLC or annunciator.
Environmental range and power loss
The 100 A continuous rating holds across the entire operating range, so no additional derating curve is needed for elevated ambient conditions.
