Breaking capacity runs 242 kA at 240 V, 187 kA at 415/440 V, 121 kA at 500 V, and 7.5 kA at 690 V; that SCCR headroom means it can sit upstream in a high-fault panel without cascading to the main breaker. The 3VA family sits in the SENTRON molded-case platform, common across IEC and UL panels for distribution and industrial feeder protection. ## Thermal derating and panel heat budget At 55 °C it derates to 385 A, at 60 °C to 370 A, at 65 °C to 355 A, and at 70 °C to 340 A. Maximum power loss is 96 W — that heat has to be considered in the enclosure thermal calculation, especially when multiple breakers are ganged in a sealed panel. Dimensions are 248 mm height, 138 mm width, 110 mm depth. The 110 mm depth (4.33 in) is within the envelope of most 200 mm deep distribution enclosures, but verify clearance for the shunt trip wiring and any auxiliary accessories that plug into the side slots.","metaTitle":"Siemens 3VA2340-6HL32-0KA0 SENTRON MCCB, 400 A, 3-Pole, Shun","metaDescription":"Siemens SENTRON 3VA2340-6HL32-0KA0 molded case circuit breaker, 400 A continuous, 3-pole, line protection, shunt trip release.
