It is designed for line protection in distribution panels and motor branch circuits, with an interrupting capacity of 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V — covering the full range of common low-voltage fault levels across IEC and UL installations. ## Ratings that govern the selection The 63 A rating holds flat from 40 °C to 50 °C, then derates to 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C — so in a warm enclosure the breaker still delivers nearly full current without nuisance tripping. The TM240 release means the thermal pickup is fixed at 240 A short-circuit threshold; the magnetic trip is non-adjustable. The breaker measures 130 mm high, 76.2 mm wide, and 70 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without special adapters. No auxiliary contacts are fitted as standard; the UVR is the only integrated auxiliary release.","metaTitle":"Siemens 3VA1163-3EF36-0BA0 SENTRON MCCB, 63 A, 3-Pole, TM240","metaDescription":"Siemens SENTRON 3VA1163-3EF36-0BA0 molded case circuit breaker, 63 A continuous at 40 °C, 3-pole, TM240 release, 75.6 kA at 240 V.
