Four poles, ETU550 electronic trip unit, and a breaking capacity that hits 242 kA at 240 V, 187 kA at 415 V, and still holds 3 kA at 690 V. That kind of interrupting muscle makes it a fit for high-fault panels where standard breakers would weld shut.
The 187 kA at 415 V confirms it handles the same class of fault on common 400 V industrial feeds. The ETU550 release gives you adjustable long-time (tr 0.5–25 s) and short-time pickup, plus ground-fault options — the N-conductor protection is adjustable OFF, 40% to 160% of Iu, so you can tune it for 4-wire systems with harmonic loads.
Lifecycle status is current — this is an active, in-production catalog item from Siemens, not a phase-out or NRND part. That means factory support, firmware updates for the ETU550, and full compliance documentation (CE, UL/CSA per the SENTRON family) are available. No last-time-buy clock ticking on this one.
Panel integration
The 3VA2025-6JP42-0AA0 measures 140 mm wide, 181 mm tall, and 86 mm deep — a 4-pole MCCB that fits standard SENTRON mounting patterns. IP40 on the front, so it's panel-front protected against tools and small solids but not washdown. Communication function is built in (yes), meaning it can talk to a higher-level system via the SENTRON communication modules — useful for energy monitoring or remote trip indication without adding a separate power meter.
