The TM120M thermal-magnetic overcurrent release handles the overload and short-circuit trip curves. What sets this one apart is the interrupting capacity: 187 kA at 240 VAC, 121 kA at 415 VAC, and still 75.6 kA at 440 V — that's serious fault-current muscle for high-capacity distribution or large motor branch circuits where the available fault current is high. ## Breaking capacity at every voltage The 3VA1163-5MH32-0HC0 carries 8.5 kA at 690 VAC — enough for 690 V line-ups, but the real story is the low-voltage side. At 240 V it clears 187 kA, so it's a fit for transformer secondaries or busway taps with massive fault current. No second-source I'd bolt in blind — the closest functional peer is the 3VA1010-2ED32-0JA0, but that's a different rating frame and release. Panel rewiring would be required. Width is 76.2 mm (standard 3-pole MCCB footprint), depth 70 mm, height 130 mm. Front IP40 protection — fine for enclosed panels, not for washdown zones. The two HQ auxiliary switches provide form-C feedback to a PLC or status lamp without an add-on module.","metaTitle":"Siemens 3VA1163-5MH32-0HC0 SENTRON MCCB, 63 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA1163-5MH32-0HC0 molded case circuit breaker, 63 A rated, 187 kA breaking capacity at 240 VAC. 3-pole, TM120M release, shunt trip.
