This 3-pole MCCB interrupts 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V. At 415 V the 187 kA still covers most industrial service-entrance requirements. The steep drop to 3 kA at 690 V means this breaker is not intended for 690 V main feeders; it belongs on a 240–500 V distribution bus.
Built-in auxiliaries and releases — what ships on the breaker
The basic switch mechanism is 3VA20106HN320AA0. No ground-fault module, no communication function, no voltage-trip feature. If you need shunt trip or GF protection, this isn't the variant.
Panel fit — dimensions and environment
That's 4.13 × 7.13 × 3.39 inches. Max power loss is 16 W — negligible for panel thermal budgeting, but worth noting if you pack breakers tightly.
