Product details

The Siemens 3VA1325-5MH32-0AA0 is a SENTRON molded case circuit breaker (MCCB) rated for 250 A continuous current at 40 °C, with a 3-pole configuration and a thermal-magnetic overcurrent release (TM120M). At 415 V and 440 V the breaking capacity holds at 121 kA; at 500 V it drops to 75.6 kA, and at 690 V it is 11.9 kA.

At 55 °C it derates to 245 A, at 60 °C to 239 A, at 65 °C to 234 A, and at 70 °C to 228 A. In a hot panel near a furnace or drive cabinet, use the 55 °C column for the ampacity budget — the TM120M release is calibrated for the thermal curve, not the ambient. Dimensions are 248 mm high by 138 mm wide by 110 mm deep. Maximum power loss is 30 W.
