Product details

That 40 A holds steady through 50 °C; above that it derates to 38.4 A at 55 °C and 36 A at 70 °C, so if your panel ambient runs hot, size the breaker for the derated number, not the nameplate. Interrupting capacity is the headline: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. Max power loss is 13.3 W.

This order code ships with two HQ auxiliary switches and an undervoltage release (UVR) factory-fitted. The supplied basic switch is 3VA10404ED320AA0, so if you're replacing an existing 3VA1040-4ED32-0CC0, that's the core assembly.

Frequently asked questions
