Breaking capacity hits 75.6 kA at 240 V, derating to 52.5 kA at 415 V and 11.9 kA at 690 V, so it clears high-fault utility feeds or transformer secondaries where the available current is serious. Rated 125 A up to 50 °C, then it steps down: 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, 114 A at 70 °C. The maximum power loss is 28.1 W, which is the heat the breaker dumps into the cabinet; factor that into your thermal budget if you're stacking several MCCBs on a DIN rail. Width is 76.2 mm (3 in) — standard 3-pole MCCB footprint for a 125 A frame. Depth is 70 mm, height 130 mm. IP40 on the front keeps dust out of the mechanism; fine for indoor panel mounting. No trip indicator, so you'll need a visual check or a remote auxiliary contact if you want panel-door indication.","metaTitle":"Siemens 3VA1112-3EE32-0AA0 SENTRON MCCB, 125 A, 75.6 kA","metaDescription":"Siemens SENTRON 3VA1112-3EE32-0AA0 molded case circuit breaker, 125 A rated at 40-50°C, 75.6 kA breaking at 240 V, 3-pole, line protection, TM220 release.
