The Siemens 3VA2325-6HN32-0AE0 is a SENTRON molded case circuit breaker (MCCB) rated for 250 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Its 3-pole construction and interrupting capacity of 242 kA at 240 V, 187 kA at 415/440 V, 121 kA at 500 V, and 7.5 kA at 690 V suit it for high-fault utility feeds and large motor branch circuits in industrial switchgear.
Integration & environment
The breaker measures 248 mm high, 138 mm wide, and 110 mm deep — sized for standard MCCB panel cutouts. Operating temperature range spans -25 °C to 70 °C, with storage from -40 °C to 80 °C, so it handles unheated enclosures in cold storage or freezer-antechamber applications without condensation concerns. Maximum power loss is 37.5 W, which factors into enclosure thermal budgeting.
