It is set at In=125A with a fixed overload Ir=125A and a non-adjustable short-circuit pickup Ii=10 x In, so the magnetic trip fires at 1250 A. The breaking capacity is Icu=25kA at 415 V AC, which is the class N level — sufficient for most downstream distribution panels in commercial and light industrial buildings where fault currents stay under that threshold. In a typical 400/415 V three-phase panel, that covers the majority of secondary-distribution scenarios. The fixed Ir (no adjustment dial) simplifies ordering — what you see on the nameplate is what you get in the panel — but also means you cannot dial it down for a lightly loaded feeder; select the exact 125 A rating for the load. Terminal connection type is listed as standard screw-clamp terminals, sized for the 125 A continuous current. When installing, maintain the manufacturer's recommended bending radius for the incoming cable and leave enough gland-plate space for the outgoing conductors — at 125 A you are likely running 35 mm² or 50 mm² copper, which needs generous bend space inside the enclosure.","metaTitle":"Siemens 3VM1112-3ED26-0AA2 Circuit Breaker, 125A, 25kA @ 415","metaDescription":"Siemens 3VM1112-3ED26-0AA2 IEC frame 160 circuit breaker, 2-pole, 125A, 25kA @ 415V.
