The interrupting capacity hits 121 kA at 240 V and still delivers 75.6 kA at 415 V, so it handles high-fault utility feeds without cascading upstream — critical for main switchboard or large subfeed applications where SCCR headroom is tight. The 63 A frame holds its rating flat from 40 °C through 50 °C, then derates to 58 A at 70 °C — a thermal curve that matters when the breaker sits in a crowded panel near other heat sources. The TM240 release means the thermal pickup is fixed at 240 A (roughly 3.8x the frame rating), so it's sized for feeder protection where the inrush of downstream motor loads or transformers won't nuisance-trip, but it's not adjustable for coordination studies that need a tighter band. Rated insulation voltage is 800 V, and the interrupting ratings at 500 V and 690 V both hold at 11.9 kA — that's the ceiling for this pole configuration. If your system runs 480 V or 600 V class, the 52.5 kA at 440 V gives a conservative benchmark; the 11.9 kA at 690 V confirms it's usable on 690 V IT networks but with reduced fault-handling. ## Panel integration Dimensions are 70 mm deep, 76.2 mm wide, and 130 mm tall — a compact 3-pole MCCB footprint that fits standard distribution panelboards and motor control center buckets.","metaTitle":"Siemens 3VA1163-4EF32-0AD0 SENTRON MCCB, 63 A, 121 kA at 240","metaDescription":"Siemens SENTRON 3VA1163-4EF32-0AD0 molded case circuit breaker, 63 A, 3-pole, line protection, TM240 release, 121 kA at 240 V.
