The Siemens SENTRON 3VA2325-7MN32-0JH0 is a 3-pole molded case circuit breaker rated for 250 A continuous current, flat across the 40 °C to 70 °C ambient range. Breaking capacity hits 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 7.5 kA at 690 V. This is a motor-protection design — phase failure detection is built in, and the trip indicator plus voltage trigger give fault visibility at the panel door. No ground-fault monitoring, no communication module, no undervoltage release on this variant.
Panel fit and auxiliaries
Dimensions are 248 mm high, 138 mm wide, 110 mm deep. The auxiliary switch block carries 2 auxiliary switches plus 1 trip alarm switch (HQ type). A shunt trip release (STL) is factory-fitted — no separate order for the coil. The basic switch core is order code 3VA2325-7MN32-0AA0. Storage range is -40 °C to 80 °C; operating range is -25 °C to 70 °C. Maximum power loss is 37.5 W, so factor that into enclosure thermal calculations.
