The Siemens SENTRON 3VA2220-7MN32-0DA0 is a 3-pole molded case circuit breaker rated 200 A continuous at 40 °C, with a breaking capacity of 330 kA at 240 V AC.
This MCCB delivers 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 5.2 kA at 690 V. The steep drop at 690 V means it is not the right choice for a 690 V main — the 5.2 kA figure is below typical fault levels in industrial 690 V distribution. For 400 V class panels, the 242 kA provides ample headroom for high-fault installations.
