Breaking capacity is the headline number here: 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and still 53 kA at 690 V. The ETU550 release provides adjustable long-time (tr from 0.5 to 25 s), short-time, instantaneous, and ground-fault protection curves, giving the selectivity engineer room to coordinate with downstream feeders. That 140 mm width is a standard 4-pole MCCB footprint — it occupies the same DIN-rail or mounting-plate pitch as other 3VA2 4-pole frames, so a panel laid out for a 3VA2025-8JQ42-0AA0 accepts this unit without drilling new holes or shifting bus bars. Front IP40 protection means the breaker face is sealed against tools and wires, but the sides and back rely on enclosure protection; mount it in a minimum IP40 cabinet. The SENTRON 3VA2 series is designed to meet IEC 60947-2 and UL 489 standards for molded case circuit breakers. The manufacturer provides RoHS and REACH declarations, along with IEC/UL certification documentation.","metaTitle":"Siemens 3VA2025-8JP46-0AA0 SENTRON MCCB, 25 A, 4-Pole, ETU55","metaDescription":"Siemens 3VA2025-8JP46-0AA0 SENTRON molded case circuit breaker, 25 A rated continuous current, 4-pole, ETU550 electronic release, 440 kA breaking capacity at 240 V.
