It's a 4-pole unit, In=500 A, with a TM240 thermal-magnetic trip, ATAM (adjustable thermal, adjustable magnetic), overload protection Ir adjustable from 350 A to 500 A, and short-circuit protection Ii adjustable from 5 to 10 times In. It also includes 100% N conductor protection and a nut keeper kit, specified for a DC Power OEM in China. ## Where it fits — panel and duty context At 500 A continuous rating, it's sized for main feeders, large motor circuits, or transformer secondary protection in industrial and commercial installations. The 4-pole configuration covers three-phase plus neutral, and the 100% N conductor protection means the neutral pole is rated to carry full phase current — relevant for systems with high harmonic content (e.g., VFD-fed loads) where neutral current can approach phase current.","metaTitle":"Siemens 3VA1450-5GF42-0AA0-ZD00 Circuit Breaker, 55kA @ 415V","metaDescription":"Siemens 3VA1450-5GF42-0AA0-ZD00 IEC frame 630 circuit breaker, breaking capacity class M Icu=55kA @ 415V, 4-pole, In=500A.
