Breaking capacity hits 440 kA at 240 V, 330 kA at 415 V, 220 kA at 500 V, and still 53 kA at 690 V — meaning this breaker can sit on the main feeder of a high-fault industrial distribution board without cascading upstream. The ETU860 electronic trip unit gives adjustable N-conductor protection (OFF, 40 % to 160 % of phase rating) and configurable short-time delay tr from 0.5 s to 25 s, so it coordinates selectively with downstream breakers on a motor control center or lighting panel. Communication function is built in — the ETU860 supports Modbus RTU via the optional COM module for power monitoring and remote trip indication.","metaTitle":"Siemens 3VA2163-8KQ42-0AA0 SENTRON MCCB, 63 A, 440 kA at 240","metaDescription":"Siemens SENTRON 3VA2163-8KQ42-0AA0 molded case circuit breaker, 63 A, 4-pole, ETU860. 440 kA breaking at 240 V.
