Product details

The Siemens 3VA2340-7HL32-0BC0 is a 3-pole SENTRON molded case circuit breaker rated for 400 A continuous current at 40 °C, with a maximum breaking capacity of 330 kA at 240 V. This is a line-protection design (not motor-protection), so it's intended for feeder or main breaker duty where the load is a distribution bus, not a single motor. The supplied basic switch is order code 3VA2340-7HL32-0AA0.

The 110 mm depth means it will clear a 120 mm deep enclosure without interference, but a 100 mm deep enclosure is too tight.
