Product details

The ENW24258 is a 4-pole EasyPact NW air circuit breaker rated 2500 A at 40 °C, built to IEC 60947-2. That 2500 A continuous rating means it carries the full load of a large distribution feeder or a big motor control center without derating—provided the ambient stays under 60 °C. The 12 kV impulse withstand (Uimp) and 1000 V rated insulation voltage (Ui) confirm it handles switching transients on a 690 V system without flashover.

Fixed mounting on a base plate, rear vertical or horizontal connections. The push-button control type is manual on the front face, with a contact position indicator for visual confirmation of open/closed state. Neutral is on the right side of the 4-pole assembly.

Frequently asked questions
