For a 63 A feeder protecting a fixed load like a panel main or a non-critical motor branch, this is a clean fit; for applications needing coordination curves, the adjustable electronic release variants in the 3VA family are the alternative. The 17 kA at 690 V still covers most 690 V motor control center bus faults. ## Auxiliary contacts and monitoring This variant ships with three auxiliary switches HQ (high-query type) integrated — no separate add-on module needed. That gives you three independent signal paths for remote status (open/closed/tripped) back to a PLC or indicator panel. Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint that drops into most SENTRON distribution blocks and panelboards without re-drilling. The front face is IP40, meaning tools or fingers won't reach live parts, but the sides and back rely on the enclosure for ingress protection. The 63 A rating holds at 40 °C, 45 °C, and 50 °C; above that it derates to 60.48 A at 55 °C and 56.7 A at 70 °C — factor that into panel ambient calculations.","metaTitle":"Siemens 3VA1163-5EF36-0AD0 SENTRON MCCB, 63 A, 187 kA at 240","metaDescription":"Siemens 3VA1163-5EF36-0AD0 SENTRON molded case circuit breaker, 63 A rated, TM240 release, 3-pole.
