Hager MCB 32A Single Pole Type D Curve NDN132A

Hager NDN132A: 32A 1 Pole D Curve Miniature Circuit Breaker (MCB) with 10kA/15kA breaking capacity for demanding overload and short-circuit protection.

Reliable Overload & Short-Circuit Protection

This mini circuit breaker combines overload protection, short-circuit protection, control, and isolation in a single trip-free device. The D curve tripping characteristic makes it suited to circuits with high inrush currents, such as motors and transformers, reducing nuisance tripping on start-up.

Safety & Reliability

A rated short-circuit breaking capacity of 10kA to BS EN 60898-2, rising to 15kA under BS EN 60947-2, gives installers confidence the device will safely clear faults on higher-demand circuits. The green "OFF" toggle position gives a clear, unmistakable visual indication of isolation status, useful during maintenance and safe isolation procedures.

Installation & Compliance

Terminals accept up to 25mm² flexible or 35mm² rigid conductors, giving installers flexibility on cable selection without changing devices. At a single modular width and IP20 rated enclosure, this Hager miniature circuit breaker fits standard consumer units and distribution boards with no special accessories required. As an active, current-production Hager product, it's suitable for new installations and like-for-like replacements on existing boards.

Compact, Space-Saving Design

Rated for 400V AC at 50Hz with a rated insulation voltage of 500V, this MCB electrical device is built for demanding three-phase and single-phase distribution boards where space and reliability both matter. The single-pole, single-module footprint helps keep panel layouts compact on busy boards.
