Product details

The Siemens SENTRON 3VA2025-7KQ32-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for 25 A continuous current, with an adjustable thermal-magnetic trip range from 38 A minimum to 300 A maximum — so it covers motor branch circuits and feeder protection where you need to dial in the trip point rather than swap the whole breaker. Breaking capacity is the headline here: 330 kA at 240 V, 242 kA at 415/440 V, 187 kA at 500 V, and 3 kA at 690 V.

Sizing and thermal performance

Power loss maxes out at 0.5 W.

Frequently asked questions

Will 3VA2025-7KQ32-0AA0 fit in a panel designed for 3VA2125-8KQ42-0AA0?

Both are 3-pole SENTRON MCCBs with the same 105 mm width, so the footprint and mounting are identical — it will drop in without rewiring or re-drilling.
