Hager 40A MCB 10kA/15kA Single Pole Type D

The Hager NDN140A is a 40A, single pole miniature circuit breaker (MCB) with a D curve that provides protection against overload currents and short circuits. The D Curve characteristic allows higher instantaneous currents before tripping, making it suitable for electrical circuits with high inrush currents.

This Hager MCB also provides circuit control and isolation, with a trip-free mechanism to ensure it trips when required, even if the toggle is held in the ON position. A green indicator on the toggle clearly shows when the breaker is in the OFF position for isolation.

The NDN140A has a 17.5mm width and accepts flexible conductors up to 25mm² or rigid conductors up to 35mm². It conforms to BS EN 60898-2 (10kA) and BS EN 60947-2 (15kA).
