It carries a breaking capacity of 187 kA at 240 V AC, 121 kA at 415/440 V, and 75.6 kA at 500 V — numbers that tell you it handles high-fault industrial service, not just branch-circuit backup.
The base switch is 3VA21105MN360AA0. No undervoltage release, no ground-fault module, no communication function — this is a straight motor-protection breaker with phase-failure detection and adjustable trip settings (4 to 17 s minimum to maximum,).
Maximum power loss is 10 W.
