At 415 V — common for industrial distribution in much of the world — 121 kA covers a high-fault panel downstream of a large transformer. The undervoltage release is built in, so a loss of control voltage trips the breaker; the auxiliary contact block includes two switches plus a separate trip alarm, which lets the PLC know the breaker opened on a fault, not a manual shutdown. At 248 mm tall, 138 mm wide, and 110 mm deep, this breaker takes a standard SENTRON 3VA cutout. The IP40 front protection means it's fine inside a closed panel; no washdown rating, so keep it out of the splash zone. Communication function onboard means it can talk to a BMS or PLC via a compatible module — useful for remote trip indication and load monitoring without running separate wires for every auxiliary contact.","metaTitle":"Siemens 3VA2463-5JQ32-0DH0 SENTRON MCCB, 630 A, 3-Pole, Line","metaDescription":"Siemens SENTRON 3VA2463-5JQ32-0DH0 molded case circuit breaker, 630 A at 40 °C, 3-pole, ETU560 trip unit, 187 kA at 240 V.
