At 240 V it interrupts 242 kA, at 415 V and 440 V it holds 187 kA, and it still clears 121 kA at 500 V. That's a high-interrupting capacity frame for fault currents that would weld a standard MCCB's contacts shut. ## Trip unit and protection logic It's a line-protection breaker, not a motor-protection device. It measures 138 mm wide, 248 mm tall, 110 mm deep — that's a three-pole frame that eats a full 138 mm of rail width, so plan your enclosure layout accordingly. At full 400 A load the maximum power loss is 96 W. That heat has to leave the enclosure; in a sealed stainless box you'll need forced ventilation or a bigger cabinet. IP40 on the front means tools and fingers stay out, but the body isn't sealed against dripping water — keep it inside the panel.","metaTitle":"Siemens 3VA2340-6HL32-0AH0 SENTRON MCCB, 400 A, ETU320","metaDescription":"Siemens 3VA2340-6HL32-0AH0 SENTRON molded case circuit breaker, 400 A rated continuous current, ETU320 electronic trip unit, 242 kA at 240 V.
