The integrated undervoltage release (UVR) drops the breaker when supply voltage falls below a threshold, which is standard for motor feeder circuits where you need coordinated shutdown on loss of control power. ## Breaking capacity across voltages — selectivity planning Breaking capacity drops as system voltage rises: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. The 63 A rating holds steady from 40 °C to 50 °C, then derates linearly to 58 A at 70 °C. In a sealed panel with multiple breakers ganged, expect to apply the 58 A figure for worst-case internal ambient. Dimensions are 70 mm deep, 76.2 mm wide, 130 mm tall — standard 3-pole MCCB footprint for DIN-rail or mounting-plate installation. The 2 HQ auxiliary switches provide status feedback for PLC or SCADA without adding external relays.","metaTitle":"Siemens 3VA1163-3EF36-0DC0 SENTRON MCCB, 63 A, 75.6 kA at 24","metaDescription":"Siemens SENTRON 3VA1163-3EF36-0DC0 molded case circuit breaker, 63 A rated, 75.6 kA breaking at 240 V. 3-pole, line protection, undervoltage release included.
