That 100 A holds steady even at 70 °C, which is unusual; most breakers start tapering above 40 °C. The interrupting ratings climb to 187 kA at 240 V, drop to 121 kA at 415/440 V, and fall off to 75.6 kA at 500 V, then 3 kA at 690 V. The supplied basic switch is 3VA20105KP320AA0. No trip indicator on the front — you'll know it tripped from the communication signal or the shunt trip circuit.
Panel fit and environment
Max power loss is 13.5 W, so no forced cooling needed in a typical ventilated enclosure. The communication function and shunt trip add wiring, but the depth leaves room behind the door for those connections.
