Product Overview
The Siemens SENTRON 3VA2325-6HN32-0AH0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, delivering 250 A continuous current across the full ambient range from -25 °C to 70 °C without derating — that means it holds its full rating even in a hot panel near a drive or transformer. Its interrupting capacity reaches 242 kA at 240 V AC, 187 kA at 415/440 V, 121 kA at 500 V, and 7.5 kA at 690 V — this part is built for high-fault installations where upstream coordination demands extreme SCCR headroom. The breaker includes a trip indicator and comes equipped with 2 auxiliary switches plus 1 trip alarm switch (HQ design), giving the panel builder or PLC direct feedback on breaker state without extra wiring.
Integration & Mounting
The 3VA2 frame measures 110 mm deep, 138 mm wide, and 248 mm high — a standard footprint for this class of MCCB, fitting into existing SENTRON panel layouts and DIN-rail or screw-mount backpanels. Power loss is rated at 37.5 W maximum, which governs ventilation spacing if the breaker is enclosed in a multi-unit lineup.
