Its interrupting capacity hits 242 kA at 240 V and 187 kA at 415/440 V, dropping to 121 kA at 500 V and 3.7 kA at 690 V. Four poles with an ETU850 electronic trip unit and a communication function onboard — this isn't a dumb thermal-magnetic; it's a communicating breaker that can report status and trip events back to a controller or BMS over the SENTRON bus. Footprint is 140 mm wide by 181 mm tall by 86 mm deep — that 140 mm width for a 4-pole MCCB is standard for the SENTRON 3VA2 frame, so it drops into the same DIN-rail or mounting-plate cutout as other 3VA2 breakers of this rating. No surprise when you're swapping one in or laying out a new panel. ## What the ETU850 trip unit brings The ETU850 is an electronic trip unit with LSIG protection (long-time, short-time, instantaneous, ground-fault) — though this specific variant ships without ground-fault monitoring. The adjustable curves let you coordinate downstream feeders without nuisance tripping, and the communication function means you can pull event logs and set parameters remotely over the SENTRON bus.","metaTitle":"Siemens 3VA2163-6KP46-0AA0 SENTRON MCCB, 63A, 4-Pole, 242kA","metaDescription":"Siemens 3VA2163-6KP46-0AA0 SENTRON molded case circuit breaker, 63A continuous, 4-pole, 242kA at 240V.
