It interrupts fault currents up to 187 kA at 240 V, 121 kA at 415 V, 121 kA at 440 V, 75.6 kA at 500 V, and 7.5 kA at 690 V — so at typical 400 V distribution voltages it clears a 121 kA bolted fault without cascading upstream breakers. At 55 °C the continuous rating drops to 385 A, at 60 °C to 370 A, at 65 °C to 355 A, and at 70 °C to 340 A. The maximum power loss is 96 W, so adjacent breakers need spacing or forced ventilation in a sealed enclosure.","metaTitle":"Siemens 3VA2340-5HN32-0KA0 MCCB, 400 A, 187 kA at 240 V","metaDescription":"Siemens SENTRON 3VA2340-5HN32-0KA0 molded case circuit breaker, 400 A rated, 187 kA interrupting at 240 V, shunt trip.
