If the breaker lives in a crowded panel with elevated internal temperature, use the 55 °C or 60 °C figure for your load calculation — not the 40 °C nameplate. The 48 W maximum power loss also contributes to enclosure heat rise; factor it into the panel thermal budget. The 140 mm width across 4 poles means it occupies standard MCCB mounting space in a distribution panel or switchboard. Front IP40 protection suits indoor panel installation where no washdown or dust ingress is expected. The ETU550 electronic trip unit draws its operating power from the line side — no auxiliary supply needed for the trip function, but the communication function (if used) requires a separate bus connection. As a Siemens SENTRON product, this MCCB carries the usual IEC/EN 60947-2 certification for molded case circuit breakers. RoHS and REACH compliance documentation is available from Siemens directly. No specific UL or CSA listing is stated in the evidence; verify local code acceptance for your jurisdiction.","metaTitle":"Siemens 3VA2225-5JP42-0AA0 MCCB 250A 4P ETU550, 187kA at 240","metaDescription":"Siemens SENTRON 3VA2225-5JP42-0AA0 molded case circuit breaker, 250 A continuous, 4-pole, ETU550 release, 187 kA at 240 V AC.
