It's the line protection variant, meaning the trip curve and accessories are set for feeder or main breaker duty, not motor circuit protection. Breaking capacity steps down as voltage rises: 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. Rated continuous current Iu holds at 125 A from 40 °C up through 50 °C, then derates to 120 A at 55 °C, 117.5 A at 60 °C, 115 A at 65 °C, and 112.5 A at 70 °C. For a panel running at 55 °C ambient, you lose 5 A of headroom — plan your load margin accordingly. Width is 76.2 mm (a standard 3-pole MCCB footprint), depth 70 mm, height 130 mm. It drops into the same DIN-rail or panel-mount cutout as other 3VA1 frames; no re-drilling if you're swapping from a 3VA1112-5EF32-0CA0, though check the shunt trip wiring since that variant may differ. ## Panel integration and accessories That covers remote trip and status feedback without adding a separate module. The overcurrent release is a TM240 thermal-magnetic unit.","metaTitle":"SENTRON 3VA1112-6EF36-0KH0 MCCB, 125 A, 220 kA at 240 V","metaDescription":"SENTRON 3VA1112-6EF36-0KH0 molded case circuit breaker, 125 A rated, 220 kA at 240 VAC. 3-pole, line protection, shunt trip, IP40 front.
