The interrupting ratings are what matter for the fault-current study: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 40 kA at 690 V — so it can sit on a high-fault panel main or feeder without upstream fuses as long as the available fault current stays under those numbers. The breaker measures 248 mm high, 138 mm wide, and 110 mm deep — a standard 3-pole MCCB footprint for a 400 A frame. It mounts on a panel backplate via screw terminals; no DIN rail, so plan for a drilled-and-tapped mounting pattern. Rated insulation voltage is 800 V, and the operating temperature range is -25 °C to 70 °C, with derating above 55 °C: 385 A at 55 °C, 370 A at 60 °C, 355 A at 65 °C, 340 A at 70 °C.","metaTitle":"Siemens 3VA2340-6HN32-0HL0 MCCB, 400 A, 3-pole, ETU350, 242","metaDescription":"Siemens SENTRON 3VA2340-6HN32-0HL0 molded case circuit breaker, 400 A, 3-pole, line protection, ETU350 release, 242 kA at 240 V.
