Hager MCB 6A Single Pole Type D Curve NDN106A

Hager NDN106A: 6A Single Pole D Curve Miniature Circuit Breaker (MCB) with 10kA/15kA short-circuit breaking capacity.

Reliable Circuit Protection

This Hager miniature circuit breaker protects the circuit against both short circuits and sustained overload current, and its trip-free mechanism means the breaker cannot be held closed against a fault. If a fault occurs, the circuit is guaranteed to open, protecting cable, connected equipment, and anyone working on the installation.

D Curve for Demanding Loads

The D tripping characteristic is designed for loads with high inrush currents, such as motors, transformers, and other switch-mode equipment. Choosing the correct curve for the application avoids nuisance tripping while still giving fast disconnection on a genuine fault, a key consideration when specifying any mini circuit breaker for commercial or industrial circuits.

Clear Isolation & Control

The toggle shows a clear green "OFF" position when the mechanism is isolated, so electricians and end users can confirm at a glance whether the circuit is safely disconnected before working on it. This visual confirmation supports safe isolation procedures on site.

Installation & Compliance

Terminals accept up to 25mm² flexible or 35mm² rigid conductors, giving installers flexibility when wiring into the consumer unit or distribution board. The breaker is tested to BS EN 60898-2 for a 10kA rated breaking capacity and to BS EN 60947-2 for 15kA, so the same Hager miniature circuit breaker satisfies both domestic and industrial short-circuit protection requirements. At a single modular width it fits standard DIN rail enclosures without taking up extra board space.
