The fixed Ir=125 A and Ii=10 x In (1250 A short-circuit pickup) make this a straight-in replacement for a line-protection breaker where you don't need adjustable overloads. The fixed thermal-magnetic trip (TM210) means no dials to mis-set; overload protection is locked at 125 A, and the magnetic short-circuit pickup is fixed at 10 times In (1250 A). That 10x multiplier is typical for motor-starting inrush on a distribution feeder, but verify it doesn't nuisance-trip on your specific load's starting current. The 100% N-conductor protection means the neutral pole is fully rated, not reduced — important for single-phase line-to-neutral faults on a 4-wire system. And the nut keeper kit is a small but real time-saver on the assembly line: no loose hardware rattling in the panel.","metaTitle":"Siemens 3VA1112-4GD42-0AA0-ZD00 Circuit Breaker, 125A, 36kA","metaDescription":"Siemens 3VA1112-4GD42-0AA0-ZD00 IEC frame 160 circuit breaker, 125A fixed thermal-magnetic, 36kA breaking capacity at 415V.
