The Siemens 3VA1112-3GE42-0AA0-ZD00 is a 4-pole IEC frame 160 molded case circuit breaker with a 125 A thermal-magnetic trip unit (TM220, ATFM). Its interrupting rating hits 25 kA at 415 V — breaking capacity class N — which means it handles moderate fault levels common in industrial distribution panels and motor control centers without cascading upstream. The overload protection band (Ir) adjusts from 88 A to 125 A, and the short-circuit pickup (Ii) is fixed at 10 times the In rating (1250 A instantaneous). This variant includes 100% neutral conductor protection and ships with a nut keeper kit for DC Power OEM applications in China.
