The 3-pole unit delivers a breaking capacity of 220 kA at 240 VAC, 154 kA at 415 VAC, and 75.6 kA at 440 VAC — figures that govern its suitability for high-fault panels where SCCR coordination is critical. The 220 kA at 240 V is the headline interrupting rating; the 154 kA at 415 V and 75.6 kA at 440 V are the values that matter for European 400 VAC panels. These are the figures a site electrical engineer uses for arc-flash incident-energy calculations and selective coordination studies. The 125 A rating holds flat from 40 °C to 50 °C, then derates linearly to 114 A at 70 °C. For a panel OEM wiring a 125 A MCCB into a 76.2 mm wide (3 in) DIN-rail footprint, the 70 mm depth and 130 mm height leave clearance for gland plates and busbar routing.","metaTitle":"Siemens 3VA1112-6EF36-0CH0 SENTRON MCCB, 125 A, 3-Pole, 220","metaDescription":"Siemens SENTRON 3VA1112-6EF36-0CH0 molded case circuit breaker, 125 A, 3-pole, 220 kA breaking capacity at 240 VAC.
