The 63 A continuous rating holds from 40 °C through 50 °C without derating; at 55 °C it drops to 62 A, at 65 °C to 60 A, and at 70 °C to 58 A — useful to know if the breaker lives in a hot enclosure or next to other heat sources. ## Integration and Auxiliary Switching The breaker ships with two factory-fitted HQ auxiliary switches, giving you status feedback for PLC inputs or alarm annunciation without adding a separate accessory. Dimensions are 130 mm height, 101.6 mm width, 70 mm depth (–) — standard SENTRON 3VA footprint for 4-pole frames, so it drops into the same panel cutout as other 3VA breakers of this size.","metaTitle":"Siemens 3VA1163-5EF42-0AC0 SENTRON MCCB, 63 A, 4-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA1163-5EF42-0AC0 molded case circuit breaker, 63 A at 40 °C, 4-pole, 187 kA breaking capacity at 240 V.
