The ETU550 electronic trip unit provides LSI protection: long-time (Ir) adjustable from 250 A to 630 A for overload, short-time (Isd) from 0.6 to 9× In for selective coordination, and instantaneous (Ii) from 1.5 to 9× In for fast clearing of hard faults. Neutral conductor protection is adjustable from OFF up to 100% of phase protection, which lets you match the breaker to a fully rated or reduced neutral bus. ## Integrated accessories — shunt trip and auxiliary switches This order code ships with a left-mounted shunt trip rated 208–277 V AC 50/60 Hz and 220–250 V DC, plus three auxiliary switches. Three aux switches give you status feedback (open/closed/tripped) for the BMS or safety PLC without adding external interposing relays. The nut keeper kit is factory-fitted, so the breaker lands on the bus bars without loose hardware falling into the enclosure.","metaTitle":"Siemens 3VA2463-5JP42-0KD0 Circuit Breaker, 630A, 55kA @ 415","metaDescription":"Siemens 3VA2463-5JP42-0KD0 IEC frame 630 circuit breaker, 55kA breaking capacity @ 415V, ETU550 LSI, 630A, shunt trip, 3 aux switches.
