Siemens SENTRON 3VA2125-7JQ32-0AA0 — 25 A MCCB, line protection, communication-ready
Its interrupting capacity reaches 330 kA at 240 V, 242 kA at 415 V, and 187 kA at 500 V, dropping to 3.7 kA at 690 V — which means it handles high-fault utility feeds at typical low-voltage levels but is not intended for 690 V distribution. A communication function allows integration with building management or power monitoring systems.
The 3-pole footprint matches typical SENTRON 3VA series cutouts — no surprises for panel builders already working with that family.
Rated continuous current is 25 A with a full-scale setting of 25 A — the breaker is fixed at that value, not adjustable. The minimum operating current is 38 A and maximum 300 A. Power loss is 0.6 W maximum.
