Why Choose the Mersen BTIA69V63 BS88 gG Fuse Link?
The Mersen BTIA69V63 is a high-performance British Standard BS88 gG fuse link designed to provide dependable overload and short-circuit protection for industrial electrical circuits. Manufactured by Mersen, this compact fuse link combines effective current limitation with a robust offset-tag construction suitable for demanding low-voltage power distribution applications.
The BTIA69V63 is intended for the full-range protection of cables, conductors, switchgear and connected electrical equipment. Its gG utilisation category means it can interrupt both overload currents and high-level short-circuit currents, helping reduce thermal and mechanical damage within an electrical installation.
With a rated current of 63 A and a rated operating voltage of 690 V AC, the Mersen BTIA69V63 is suitable for industrial control panels, distribution boards, machinery and switchgear systems requiring reliable circuit protection in a compact BS88 format.

Reliable Protection for Industrial Electrical Systems
The Mersen BTIA69V63 protects electrical installations by interrupting excessive current before it can cause serious damage to cables, switchgear or connected equipment. During an overload or short circuit, the internal fuse element operates rapidly to isolate the affected circuit and limit the fault energy allowed to pass.
Its gG operating characteristic provides comprehensive protection across the complete current range. This makes the fuse suitable for panel builders, electrical contractors and maintenance engineers working with industrial power distribution, machinery and control equipment.
Typical Applications
- Industrial control panels.
- Electrical distribution boards.
- Low-voltage switchgear.
- Fuse switch disconnectors.
- Industrial machinery and automation systems.
- Cable, conductor and equipment protection.
