Why Choose the Mersen BTC69V63 BS88 gG Fuse Link?
The Mersen BTC69V63 is a dependable British Standard BS88 gG fuse link designed to protect industrial electrical circuits against damaging overload and short-circuit currents. Manufactured by Mersen, it provides effective current limitation to help safeguard cables, conductors, switchgear and connected equipment during electrical fault conditions.
Its gG full-range operating characteristic enables the BTC69V63 to provide protection against sustained overloads and high-level short circuits. A robust ceramic body and bolted-tag construction support secure mechanical and electrical installation within compatible fuse holders, fuse switches and distribution assemblies.
With a rated current of 63 A and a rated operating voltage of up to 690 V AC, the Mersen BTC69V63 is suitable for control panels, switchboards, industrial machinery and power distribution systems requiring reliable circuit protection at elevated operating voltages.

Reliable Protection for Industrial Electrical Systems
The Mersen BTC69V63 operates by interrupting excessive electrical current before it can cause serious damage to cables, switchgear or connected equipment. During an overload or short circuit, the internal fuse element isolates the affected circuit and limits the amount of damaging fault energy allowed to pass.
Its gG operating characteristic provides protection across the complete current range, making the fuse link suitable for panel builders, electrical contractors and maintenance engineers working with industrial machinery, control equipment and power distribution systems.
Typical Applications
- Industrial control panels.
- Electrical distribution boards.
- Low-voltage switchgear.
- Fuse switches and switch disconnectors.
- Industrial machinery and automation equipment.
- Cable, conductor and equipment protection.
