Its breaking capacity hits 440 kA at 415 V and 187 kA at 690 V, so it can clear high-fault scenarios without cascading upstream — a key spec for transformer secondaries or large bus risers where available fault current is high. The 63 A rating holds flat across the full ambient range from 40 °C to 70 °C, meaning no derating headache in a warm enclosure. The adjustable N-conductor protection (OFF, 40 % to 160 %) gives the panel builder flexibility for 4-wire systems where neutral protection requirements vary by local code or transformer configuration. Communication function is built in, so it can report status to a BMS or PLC without an add-on module. ## Trip unit and protection range The ETU860 electronic trip unit covers an adjustable overload range from 95 A to 756 A (the minimum and maximum settings), so this single frame size can serve multiple load tiers by dialing the trip threshold.","metaTitle":"Siemens 3VA2163-0KQ42-0AA0 SENTRON MCCB, 63 A, 440 kA at 415","metaDescription":"Siemens SENTRON 3VA2163-0KQ42-0AA0 molded case circuit breaker, 63 A continuous, 440 kA breaking capacity at 415 V.
