Hager MCB 32A Triple Pole Type D Curve NDN332A

Hager NDN332A: 32A Miniature Circuit Breaker (MCB) with D Curve tripping characteristic, 3 Pole configuration and 10kA breaking capacity.

Safety & Reliability

This miniature circuit breaker protects circuits against both short circuits and overload current, with a trip free mechanism that ensures the breaker operates correctly even if the toggle is held in. For installers specifying a mini circuit breaker on 3 phase distribution boards, the D curve rating suits loads with higher inrush currents. Breaking capacity is rated at 10kA to BS EN 60898-2 and 15kA to BS EN 60947-2, giving confidence on circuits with higher fault levels.

Control & Access

Isolation status is shown clearly on the toggle, with the "OFF" position marked in green so electricians and maintenance staff can confirm at a glance that a circuit is safely isolated before working on it.

Installation & Compliance

The 3 module width keeps panel space to a minimum in consumer units and distribution boards. Connection capacity covers 25mm² flexible conductor and 35mm² rigid conductor, while the IP20 enclosure rating and -25°C minimum operating temperature suit a wide range of installation environments. As a Hager miniature circuit breaker built to BS EN 60898-2 and BS EN 60947-2, it provides documented compliance for sign-off and certification.
