Breaking capacity is the real selector here: 187 kA at 240 V, 121 kA at 415/440 V, 79 kA at 500 V, and 5.1 kA at 690 V. The line protection version means it's configured for feeder protection rather than motor or generator duty. The 5SQ series is the older frame; the 3VA2 is the current platform. Check the mounting hole pattern against your existing panel layout before committing the order. In a washdown or outdoor enclosure, the breaker itself needs a sealed cabinet; the IP40 rating covers the operator interface only. Maximum power loss is 48 W.","metaTitle":"Siemens 3VA2225-5HN42-0AH0 SENTRON MCCB, 250 A, 4-Pole, ETU3","metaDescription":"Siemens SENTRON 3VA2225-5HN42-0AH0 molded case circuit breaker, 250 A rated continuous current, 4-pole, ETU350 electronic trip unit.
