That kind of SCCR headroom makes it a good fit for the main or feeder position in a panel where fault current is high. The 400 A rating holds up to 50 °C ambient. Above that it starts to step down: 384 A at 55 °C, 376 A at 60 °C, 368 A at 65 °C, and 360 A at 70 °C. The maximum power loss is 66 W, which adds to the enclosure heat load. Mounting it with some breathing space around the vents helps keep the internal trip unit cool. ## Built-in undervoltage release and auxiliary contacts The auxiliary contacts give you status feedback: open/closed indication back to the PLC or a remote panel. ## Physical fit in the panel That's a standard SENTRON 3VA2 frame size — it bolts onto a mounting plate or a DIN rail adapter. Terminal layout follows the usual line-top / load-bottom convention; busbar kits and cable connectors are available from the same SENTRON accessory range.","metaTitle":"Siemens 3VA2440-5HL32-0BC0 SENTRON MCCB, 400 A, 3-Pole, Line","metaDescription":"Siemens SENTRON 3VA2440-5HL32-0BC0 molded case circuit breaker, 400 A, 3-pole, line protection, ETU320 trip unit, 187 kA at 240 V.
