Its interrupting capacity reaches 440 kA at 415 V AC and 187 kA at 690 V AC, which means it can clear high-fault currents on the line side of a distribution panel without upstream fuses needing to open — useful for main or feeder protection in high-SCCR installations. The ETU350 release supports adjustable N-conductor protection (OFF, 50%, 100%) and is designed for line protection, not motor or generator duty — it's a distribution breaker, not a motor circuit protector. The 250 A continuous rating holds flat from 40 °C through 70 °C ambient — no derating needed across the typical panel temperature range, which simplifies panel design for enclosures with marginal cooling. Operating ambient spans -25 °C to 70 °C; storage range is -40 °C to 80 °C, so the breaker can sit in an unheated warehouse without issue. Maximum power loss is 37.5 W — a moderate figure for a 250 A frame; plan for that heat rejection in a sealed enclosure, especially if multiple breakers are ganged. Dimensions are 248 mm high, 184 mm wide, 110 mm deep — a standard 4-pole MCCB footprint that fits most DIN-rail or screw-mount panel layouts without modification. If you need remote trip or status feedback, look at the 3VA2 with communication option.","metaTitle":"Siemens 3VA2325-0HN42-0AA0 SENTRON MCCB, 250 A, 4-Pole, ETU3","metaDescription":"Siemens SENTRON 3VA2325-0HN42-0AA0 molded case circuit breaker, 250 A continuous, 4-pole, ETU350 release, 440 kA at 415 V.
