Breaking capacity runs 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V — a steep drop above 415 V, so if your fault current is high on a 480 V or 690 V system, check the coordination study against the 32 kA or 10.5 kA limit before committing the BOM line. The integrated auxiliary trip uses order code 3VA9608-0BB11 if you need to add a shunt or UVR later. Front protection is IP40 — fine for a dry enclosure, not for washdown. Latching endurance is 15 000 operations.","metaTitle":"Siemens 3VA1112-3EF36-0BH0 SENTRON MCCB, 125 A, 3-Pole, TM24","metaDescription":"Siemens 3VA1112-3EF36-0BH0 SENTRON molded case circuit breaker, 125 A rated, 3-pole, TM240 release, 75.6 kA at 240 V.

It will not drop into the same panel footprint without rewiring — the 3VA1112-3EF36-0BH0 has a 76.2 mm width versus the 3VA1010's narrower frame, so busbar spacing and mounting holes differ.
