Its breaking capacity hits 242 kA at 240 V, 187 kA at 415/440 V, 121 kA at 500 V, and 7.5 kA at 690 V — so at typical 480 V distribution levels you've got serious fault-current headroom. The adjustable thermal-magnetic trip is set from 80 A to 400 A full-scale, meaning you dial in the actual load, not just accept a fixed threshold. The 110 mm depth keeps it clear of shallow enclosure doors; verify the dead-front clearance if your panel has a rear-mounted bus stack. ## Auxiliary and communication It ships without auxiliary switches, so if you need status feedback to a PLC, plan to add a separate auxiliary switch block. Maximum power loss is 96 W at rated current, which matters for enclosure thermal calculations in a multi-breaker lineup.","metaTitle":"Siemens 3VA2340-6JQ32-0HA0 SENTRON MCCB, 400 A, 3-Pole, 242","metaDescription":"Siemens SENTRON 3VA2340-6JQ32-0HA0 molded case circuit breaker, 400 A, 3-pole, 242 kA at 240 V.
