Product details

What the interrupting ratings mean for your panel

The Siemens SENTRON 3VA1050-4ED32-0HA0 is a 3-pole molded case circuit breaker rated 50 A continuous at 40 °C, with a TM210 thermal-magnetic overcurrent release and an integral shunt trip (STL) for remote tripping. Its interrupting capacity reaches 121 kA at 240 VAC, 75.6 kA at 415 VAC, and 52.5 kA at 440 VAC — figures that govern whether this breaker clears a fault without upstream devices needing to open. At 500 V and 690 V the rating drops to 11.9 kA, so verify the available fault current at your service voltage before specifying.
