It carries the ETU550 electronic trip unit configured for LSI protection (long-time, short-time, instantaneous) with a rated continuous current In of 1000 A and an adjustable overload pickup Ir from 400 A to 1000 A. This is a line-protection breaker, not a motor-circuit protector; the LSI curve suits distribution feeders and large loads where selective coordination matters. In a panel with a transformer secondary or a large bus feeding a 1000 A feeder, that rating gives headroom for most industrial installations without cascading upstream. The ETU550 LSI trip allows coordination: Isd adjustable 0.6–10× In covers short-time delay for selectivity with downstream breakers; Ii adjustable 1.5–10× In sets the instantaneous pickup. Neutral protection is adjustable (OFF up to 100 % of phase current). The shunt trip accessory means this breaker can be remotely tripped by a safety circuit or emergency-stop system — the left-side coil draws from 208–277 V AC or 220–250 V DC, so it integrates directly into common control voltages without an interposing relay. ## Deployment context This breaker mounts in a standard IEC switchboard or distribution panel — it is a fixed (not drawout) frame 1000 unit, so plan for busbar connection and sufficient enclosure volume for cable bending radius. The nut keeper kit (included per the description) secures the terminals against vibration in high-ambient environments like cement plants or steel mills. The electronic trip unit is field-configurable; the rotary dials for Ir, Isd, Ii, and neutral protection are accessible through the cover without removing the breaker.","metaTitle":"Siemens 3VA2510-5JP42-0KA0 1000A Circuit Breaker, 55kA @ 415","metaDescription":"Siemens 3VA2510-5JP42-0KA0 IEC frame 1000 circuit breaker, 55kA breaking capacity at 415V, ETU550 LSI protection, shunt trip.
