Product details

Siemens SENTRON 3VA1325-5MH32-0AH0 — 250 A MCCB with TM120M trip unit

The Siemens SENTRON 3VA1325-5MH32-0AH0 is a 3-pole molded case circuit breaker rated at 250 A continuous, fitted with a TM120M thermal-magnetic overcurrent release. It carries a 187 kA interrupting rating at 240 VAC, stepping down to 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 11.9 kA at 690 V — the curve tells you where this breaker is comfortable and where it needs upstream coordination. The 250 A frame holds its full rating up to 50 °C ambient; above that it derates linearly to 228 A at 70 °C, which matters if this lands in a hot panel next to drives or transformers.

Mounting and footprint

Dimensions are 248 mm high, 138 mm wide, 110 mm deep — a standard SENTRON 3VA frame size that fits the usual DIN-rail or screw-mount pattern in a distribution panel. Auxiliary switch configuration is 2 aux switches plus 1 trip alarm switch (HQ), already built into the supplied basic switch 3VA13255MH320AA0.

Frequently asked questions

What is the breaking capacity of 3VA1325-5MH32-0AH0 at different voltages?

Rated 187 kA at 240 VAC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 11.9 kA at 690 V — the interrupting rating drops significantly above 500 V, so check coordination if your fault current is high on a 690 V system.
