The TM240 thermal-magnetic release handles the overload and short-circuit curve. Breaking capacity runs 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V — that 220 kA figure at 240 V tells you this breaker is sized for high-fault industrial panels, not light commercial. Front IP40 protection means it's fine inside a clean enclosure; not rated for washdown zones. The breaker measures 130 mm high, 76.2 mm wide, and 70 mm deep — the 3-pole width is a standard 3-inch (76.2 mm) footprint, so it drops into existing SENTRON or 3VA panel cutouts without re-drilling.","metaTitle":"Siemens 3VA1112-6EF36-0AA0 SENTRON MCCB, 125 A, 3-Pole, 220","metaDescription":"Siemens SENTRON 3VA1112-6EF36-0AA0 molded case circuit breaker, 125 A, 3-pole, TM240 release.
