Hager MCB 10A Single Pole Type D Curve NDN110A

Hager NDN110A: 10A 1 Pole D Curve Miniature Circuit Breaker (MCB) with 10kA/15kA breaking capacity for demanding overload and short-circuit protection.

Safety & Reliability

This mini circuit breaker combines short-circuit protection, overload protection, and isolation in a single compact module. A trip-free mechanism means the contacts open on a fault even if the toggle is held in, so the circuit cannot be forced back on while a fault condition persists.

Rated to 10kA under BS EN 60898-2 and 15kA under BS EN 60947-2, this Hager miniature circuit breaker gives installers confidence on both domestic consumer units and light commercial distribution boards where higher prospective fault currents are expected.

Clear Isolation & Control

The toggle shows a clear green "OFF" position when isolated, so electricians and maintenance staff can confirm circuit status at a glance without testing. This reduces time spent on site during fault-finding or planned isolation work.

Installation & Compliance

Terminals accept up to 25mm² flexible or 35mm² rigid conductors, covering the vast majority of final circuit and sub-main applications without needing adaptors. At just one modular width, this mcb electrical device keeps panel layouts compact.

Built to BS EN 60898-2 and BS EN 60947-2, it's suitable wherever a compliant D-curve device is specified, including circuits with higher inrush currents such as motors and transformers. A Wylex miniature circuit breaker or Hager miniature circuit breaker, both must meet the same recognised standards, and this device is fully compliant.
