It is configured for line protection with a TM240 thermal-magnetic trip unit, ATAM (adjustable thermal, adjustable magnetic) overload protection set from 88 A to 125 A, and short-circuit protection adjustable from 5 to 10 times In. The N conductor is fully protected (100% rating). This variant includes a nut keeper kit and is specified for a DC Power OEM application in China. The adjustable thermal overload (Ir = 88–125 A) lets you dial in the exact motor or feeder FLA without swapping trip units. The 5–10x In magnetic adjustment range covers motor inrush (typically 6–8x FLA) while still providing short-circuit protection. Full N-conductor protection (100% rated) means the neutral pole is not undersized for unbalanced loads or harmonic currents.","metaTitle":"Siemens 3VA1112-4GF42-0AA0-ZD00 Circuit Breaker, 125A, 36kA","metaDescription":"Siemens 3VA1112-4GF42-0AA0-ZD00 IEC frame 160 circuit breaker, 125A, 36kA breaking capacity at 415V.
