The long-time pickup Ir is adjustable from 320 A to 800 A, short-time Isd from 1.5 to 10 times Ir, and instantaneous Ii fixed at 12 times In — so you can shape the curve to coordinate with downstream feeders without sacrificing arc-flash reduction. Neutral protection is selectable: OFF, 50%, or 100% of phase pickup. That matters when the neutral conductor is undersized or when you need full neutral protection on a four-wire system feeding nonlinear loads. Comes with two changeover auxiliary switches built in — no separate add-on block needed for status feedback to the PLC or SCADA.","metaTitle":"Siemens 3VA2580-6HN42-0AB0 Circuit Breaker, 85kA @ 415V, 800","metaDescription":"Siemens 3VA2580-6HN42-0AB0 IEC frame 1000 circuit breaker, 85kA breaking capacity @ 415V, 4-pole, ETU350 LSI, 800A.
