Breaking capacity is 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V — those numbers tell you the maximum fault current it can safely interrupt at each voltage level, so the panel designer sizes the upstream transformer and bus bracing accordingly. ## Thermal derating and real-world mounting At 55 °C it derates to 60.48 A, at 60 °C to 59.22 A, at 65 °C to 57.96 A, and at 70 °C to 56.7 A. The front face is IP40, so it keeps out tools and fingers but not fine dust; mount it inside a sealed enclosure if the atmosphere is gritty. Dimensions are 70 mm deep, 76.2 mm wide, and 130 mm tall — a standard 3-pole MCCB footprint that fits most DIN-rail or screw-mount panel layouts without re-drilling. ## Auxiliary contacts and release options It ships with two auxiliary switches HQ — those are the signal contacts that tell a PLC or indicator light whether the breaker is open or closed. The overcurrent release is the TM240, a fixed thermal-magnetic unit with a maximum adjustable response time of 1 second — not a solid-state electronic trip.","metaTitle":"Siemens 3VA1163-3EF32-0AC0 SENTRON MCCB, 63 A, 3-Pole, TM240","metaDescription":"Siemens 3VA1163-3EF32-0AC0 SENTRON molded case circuit breaker, 63 A rated, 3-pole, TM240 thermal-magnetic release.
