MCCB for line protection with shunt trip
At 415 V and 440 V the rating holds at 121 kA, dropping to 75.6 kA at 500 V and 3.7 kA at 690 V, so the SCCR coordination study should reference the actual line-to-line voltage of the installation. It does not carry undervoltage release or ground-fault monitoring, so those functions would need external modules if required. The 10 W maximum power loss is modest for a 100 A frame, keeping panel heat rise manageable in a densely packed enclosure.
The breaker occupies 105 mm width, 181 mm height, and 86 mm depth — a standard 3-pole MCCB footprint for the 100 A frame class. The 86 mm depth (3.39 in) leaves clearance behind the panel door for wiring and auxiliary wiring channels.
