Short-circuit pickup Ii is adjustable 5 to 10 times In (625 A to 1250 A at the 125 A setting), enough to ride through motor inrush without nuisance tripping. This breaker mounts into a standard DIN-rail enclosure or panel-mount base. The 4-pole configuration with an unprotected N conductor suits 3-phase + neutral systems where the neutral doesn't need its own overcurrent protection — common in North American-style panelboards or OEM switchgear. The nut keeper kit is a small but welcome detail for DC Power OEM builds in China; it keeps the terminal hardware from walking loose under vibration on a factory floor.","metaTitle":"Siemens 3VA1112-5EF42-0AA0-ZD00 Circuit Breaker, 125A, 55kA","metaDescription":"Siemens 3VA1112-5EF42-0AA0-ZD00 IEC frame 160 circuit breaker, 4-pole, 125A, 55kA breaking capacity at 415V.
