Interrupting capacity hits 75.6 kA at 240 V, 52.5 kA at 415 V, and 11.9 kA at 690 V. Power loss maxes at 30.6 W, so factor that into enclosure heat calculations. Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — standard 3-pole MCCB footprint for a SENTRON panel. The UVR is the design-of-auxiliary-release type, so verify your control circuit voltage matches the release coil rating before wiring.","metaTitle":"Siemens 3VA1112-3EF36-0DA0 SENTRON MCCB, 125 A, 3-Pole, UVR","metaDescription":"Siemens SENTRON 3VA1112-3EF36-0DA0 molded case circuit breaker, 125 A rated at 40 °C, 3-pole, with TM240 overcurrent release and undervoltage release. 75.6 kA at 240 V.
