It ships with a TM240 thermal-magnetic trip unit: In=320A, Ir adjustable from 224A to 320A, Ii adjustable from 5 to 10 times In. The N conductor is protected at 100% of the phase rating — a detail that matters for 4-wire distribution panels where the neutral carries harmonic or unbalanced current. ## Integration notes Mounts in a standard IEC panel — the 4-pole footprint occupies the same DIN-rail or bolted-backplane space as other 3VA1 frame breakers, so a panel layout already designed for a 3VA1 accepts this unit without re-drilling. The nut keeper kit (included per the order-code suffix) is specified for DC Power OEM assembly in China — it retains the terminal nuts during vibration, which is a practical concern for breakers shipped inside pre-wired enclosures.","metaTitle":"Siemens 3VA1332-4GF42-0AA0-ZD00 Circuit Breaker, 36kA @ 415V","metaDescription":"Siemens 3VA1332-4GF42-0AA0-ZD00 IEC frame 400 circuit breaker, breaking capacity class S, Icu=36kA @ 415V, 4-pole, TM240, In=320A, Ir=224-320A, Ii=5-10xIn.
