Hager NCN325A 25A MCB TP Type C Curve 10kA

Hager NCN325A: 25A 3 Pole C Curve Miniature Circuit Breaker (MCB) with 10kA/15kA short-circuit breaking capacity and 3 module width for compact consumer unit installations.

Safety & Reliability

This Hager miniature circuit breaker protects circuits against both short circuits and sustained overload current, tripping automatically before conductors or connected equipment are damaged. The trip-free mechanism means the breaker cannot be held closed against a fault, so protection is guaranteed even if someone attempts to override it. Rated short-circuit breaking capacity is 10kA to BS EN 60898-2 and 15kA to BS EN 60947-2, giving installers a mini circuit breaker with headroom on higher fault-level installations.

Clear Isolation & Control

The toggle switch doubles as a local isolator, and the isolated state is confirmed by a green "OFF" mechanical indicator on the switch body. Engineers get an unambiguous visual check that the circuit is dead before working on it, reducing the risk of live working errors on site.

Installation & Compliance

Terminals accept up to 25mm² flexible or 35mm² rigid conductors, covering typical final circuit and sub-main wiring without needing adaptors. At just 3 modules wide for a 3 pole device, this Hager MCB electrical unit saves space in busy distribution boards. It conforms to BS EN 60898-2 (10kA) and BS EN 60947-2 (15kA), so it's suitable as a direct like-for-like replacement or new install on Hager and compatible Wylex miniature circuit breaker boards using standard DIN rail mounting.

Built for Demanding Environments

Rated for continuous operation from -25°C, this hager miniature circuit breaker holds its rated 400V AC performance in cold plant rooms, garages, and outbuildings as well as standard indoor consumer units. An IP20 enclosure rating and pollution degree 2 classification confirm it's designed for standard indoor electrical enclosures.
