It carries an ETU350 LSI trip unit, rated at 800 A continuous, with adjustable overload protection (Ir) from 320 A to 800 A and short-circuit protection (Isd) from 1.5 to 10 × Ir. The ETU350 is a microprocessor-based trip unit giving you LSI (long-time, short-time, instantaneous) curves, so you can coordinate selectively with downstream breakers. The adjustable N-conductor protection (OFF, 50%, 100%) lets you match the neutral to the phase load on a 4-wire system, common in North American-style mining substations. ## Integration notes The shunt trip (208–277 V AC / 220–250 V DC) on the left side fires on a control signal; wire it through an E-stop relay or a remote trip pushbutton. Two auxiliary switches are factory-fitted for status feedback to the PLC or SCADA.","metaTitle":"Siemens 3VA2580-5HN42-0KC0 Circuit Breaker, 800A, 55kA @ 415","metaDescription":"Siemens 3VA2580-5HN42-0KC0 IEC frame 1000 breaker, 4-pole, 55kA @ 415V, ETU350 LSI, 800A, shunt trip.
