It carries 154 kA at 415 V, which is the figure that governs fault clearance in a 400 V-class distribution panel; the 220 kA at 240 V and 75.6 kA at 440 V give you the selectivity headroom for high-fault installations like transformer secondaries or large motor control centers. The 125 A rating holds steady from 40 °C through 50 °C (still 125 A at 50 °C), then derates gradually to 114 A at 70 °C — so in a warm enclosure you still get most of the nameplate current without having to oversize the breaker. The TM220 trip unit is the fixed thermal-magnetic type; no electronic adjustment or communication function, which keeps it simple and reliable for line-protection duty in standard distribution panels. Max power loss is 28.1 W, which matters for enclosure heat budgeting — in a packed panel with several breakers, that figure adds up fast and can drive ventilation decisions. ## Integration Notes Three-pole design, 76.2 mm wide (roughly 3 inches) — fits standard DIN-rail or panel-mount footprints common in SENTRON and 3VA-series enclosures. Depth is 70 mm, height 130 mm. Front IP40 protection class keeps dust and tools out but isn't rated for washdown; mount it inside a sealed cabinet if the environment is wet or dusty. If you need shunt trip or remote status, you're looking at a different variant in the 3VA family.","metaTitle":"Siemens 3VA1112-6EE36-0AA0 SENTRON MCCB, 125 A, 3-Pole, 154","metaDescription":"Siemens 3VA1112-6EE36-0AA0 SENTRON molded case circuit breaker. 125 A continuous, 3-pole, TM220 trip unit. 154 kA breaking capacity at 415 V.
