Product details

What the 250 A rating and interrupting capacity mean for your panel

The Siemens SENTRON 3VA1225-6GF42-0AF0 is a 4-pole molded case circuit breaker rated 250 A continuous at 40 °C, with a TM240 thermal-magnetic release sized for line protection. That 250 A holds flat through 50 °C — above that, the thermal curve derates to 243 A at 55 °C, 237 A at 60 °C, 230 A at 65 °C, and 223 A at 70 °C. This breaker delivers 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V.

Maximum power loss is 57 W.
