Rated In=500A with overload protection adjustable from 200A to 500A, it delivers a breaking capacity of 55kA at 415V (class M), which means it can safely interrupt fault currents up to that level on a 415V three-phase line without cascading upstream — critical for maintaining selectivity in a distribution panel. The nut keeper kit (included) retains the lug nuts during wiring — a detail that saves time when the panel builder is working in a tight gland plate area. The 4-pole configuration covers three-phase plus neutral, with the N-conductor protection adjustable from OFF to 100% of the phase setting. The ETU550's LSI curve allows coordination downstream with smaller breakers or fused disconnects, giving the site electrical engineer the headroom to design a selective distribution scheme.","metaTitle":"Siemens 3VA2450-5JP42-0AF0 3VA2 IEC Frame 630, 55kA @ 415V,","metaDescription":"Siemens 3VA2450-5JP42-0AF0 circuit breaker, 3VA2 IEC frame 630, 55kA breaking capacity @ 415V, 4-pole, ETU550 LSI, In=500A.
