Hager Type B Curve MCB 63A Single Pole 6kA MTN163

Hager MTN163: 63A Single Pole B Curve Miniature Circuit Breaker (MCB) with 6kA breaking capacity for domestic circuit protection.

Safety & Reliability

This Hager miniature circuit breaker protects circuits against overloads and short circuits, tripping automatically before wiring or connected equipment is damaged. The B curve characteristic makes it well suited to lighting circuits and general resistive loads found in domestic installations, while the 6kA rated short-circuit breaking capacity (Icn, tested to BS EN 60898) gives installers a proven safety margin. A higher Icu rating of 10kA under IEC 60947-2 confirms the device retains integrity even after a serious fault event.

Installation & Compliance

Full compliance with BS EN 60898 means this mini circuit breaker meets the recognised UK and European standard for domestic overcurrent protection, so it can be specified with confidence on notifiable and non-notifiable electrical work alike. The 400V rated voltage and 50Hz frequency match standard UK AC supplies, and a rated insulation voltage of 500V plus a 4kV impulse withstand rating add extra headroom against transient surges.

Compact, Space-Saving Design

At just one modular width (17.5mm), this MCB electrical device takes up minimal space inside a consumer unit or distribution board, letting installers fit more protection into tight enclosures. An IP20 degree of protection guards against accidental contact with live parts once the board is closed, and a pollution degree 2 rating confirms suitability for normal indoor environments.
