The In=125A continuous rating with adjustable overload protection Ir=88A...125A gives you a 37 A band to dial in the exact motor or feeder load without swapping the breaker body. Mounts on DIN rail in a standard panel enclosure. The 4-pole footprint (3 poles + unprotected N) matches the common 3-phase + neutral busbar layout for IEC switchgear. Terminal connections accept copper or aluminum conductors up to the frame's rated cross-section — verify lug sizing against the 125 A continuous current for your specific wire type.","metaTitle":"Siemens 3VM1112-5EE46-0AA2 Circuit Breaker, 125A, 55kA @ 415","metaDescription":"Siemens 3VM1112-5EE46-0AA2 circuit breaker, 3VM1 IEC frame 160, 4-pole, 125A, Icu=55kA @ 415V.
