The Siemens SENTRON 3VA2325-6HN32-0JC0 is a 3-pole molded case circuit breaker rated for 250 A continuous current across the full 40–70 °C ambient range — no derating needed as the panel warms up. Its interrupting capacity is voltage-dependent: 242 kA at 240 V, 187 kA at 415/440 V, 121 kA at 500 V, and 7.5 kA at 690 V.
Line protection with integrated shunt trip
This MCCB is designed for line protection (cable/feeder) rather than motor or generator protection — the trip curve and accessories are tuned for overcurrent on distribution circuits. The basic switch core is order code 3VA2325-6HN32-0AA0.
Dimensions are 110 mm deep × 138 mm wide × 248 mm high. Maximum power loss is 37.5 W, so account for that heat in a sealed enclosure.
