Its ETU550 electronic trip unit provides LSI protection — long-time (Ir adjustable 100–250 A), short-time (Isd 0.6–10× In), and instantaneous (Ii 1.5–10× In) — plus adjustable neutral protection (OFF to 100 %), which gives the site engineer the selectivity curves needed to coordinate downstream branch breakers without nuisance tripping on motor inrush. The 4-pole form factor occupies roughly 280 mm of DIN width; account for the UVR coil draw when sizing the control transformer feeding the 208–230 V AC circuit. The auxiliary and alarm switches (both HQ type) provide volt-free changeover contacts for remote status indication — wire the trip alarm into the PLC's safety input chain so a breaker trip is visible at the HMI without a separate monitoring relay.","metaTitle":"Siemens 3VA2225-5JP42-0DF0 Circuit Breaker, 55kA @ 415V, 250","metaDescription":"Siemens 3VA2225-5JP42-0DF0 IEC frame 250 circuit breaker, 55kA breaking capacity @ 415V, ETU550 LSI protection, 250A rated.
