Hager 20A MCB 10kA/15kA Single Pole Type B

The Hager NBN120A is a 20A, single pole miniature circuit breaker (MCB) with a B curve that provides protection against overload currents and short circuits. The B Curve characteristic trips at lower multiples of its rated current than C and D Curve MCBs, making it suitable for circuits with low 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 NBN120A 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).
