Product details

Rated continuous current and breaking capacity

The Siemens SENTRON 3VA1340-5GF42-0AA0 is a 4-pole molded case circuit breaker rated for 400 A continuous current at 40 °C, with the TM240 thermal-magnetic overcurrent release. Its interrupting capacity reaches 187 kA at 240 V AC, 121 kA at 415/440 V, 75.6 kA at 500 V, and 11.9 kA at 690 V — so it handles high-fault utility feeds and transformer secondaries without cascading upstream.

Above that it derates linearly: 392 A at 55 °C, 384 A at 60 °C, 376 A at 65 °C, and 367 A at 70 °C.

Physical integration

Dimensions are 248 mm high, 184 mm wide, and 110 mm deep. The 4-pole footprint fits standard panel-mount cutouts for SENTRON 3VA frames.
