Product details

The interrupting ratings span 52.5 kA at 240 VAC down to 7.5 kA at 690 VAC, which covers most industrial distribution panels up to the 690 V class.

At 415 V the breaker clears 32 kA; at 440 V it clears 13.6 kA. The 7.5 kA rating at 690 V is typical for a 50 A frame in a 690 V motor control center.

There is no undervoltage release fitted as standard.

The breaker is rated 50 A from 40 °C through 50 °C, then derates linearly to 45 A at 70 °C. Maximum power loss is 14.6 W per pole — relevant for enclosure heat rise calculations when grouping several breakers in a panel.
