Its interrupting capacity hits 187 kA at 240 V, tapering to 121 kA at 415 V and 75.6 kA at 440 V — numbers that tell you this breaker is built for high-fault panels where SCCR headroom matters. An integrated undervoltage release (UVR) is included, which means the breaker can be tripped remotely by dropping the control voltage — common in emergency-stop or safety interlock circuits. ## Thermal derating and power dissipation in the panel At 55 °C it derates to 62 A, at 60 °C to 61 A, at 65 °C to 60 A, and at 70 °C to 58 A. If your enclosure ambient runs above 50 °C, you lose about 1 A per 5 °C rise. Maximum power loss is 19.8 W — modest for a 63 A frame, but worth checking against your panel's thermal budget if you're stacking multiple breakers in a sealed box. Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep, which is the standard 3VA1 frame footprint; it clips onto a DIN rail or mounts via the screw terminals. ## What the UVR adds to the circuit This is standard for applications where you want the breaker to open on loss of control power — think safety circuits, emergency-off chains, or interlocked machine zones.","metaTitle":"Siemens 3VA1163-5ED32-0CA0 MCCB, 63A, 3-Pole, 187kA at 240V","metaDescription":"Siemens SENTRON 3VA1163-5ED32-0CA0 molded case circuit breaker, 63A rated at 40°C, 3-pole, 187kA interrupting at 240V.
