Why Choose the Mersen BTC69V50 BS88 gG Fuse Link?
The Mersen BTC69V50 is a dependable British Standard BS88 gG fuse link designed to protect industrial and commercial electrical circuits against 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 BTC69V50 to interrupt both sustained overload currents and high-level short circuits. The robust ceramic construction and bolted-tag terminal arrangement support secure installation in compatible fuse holders, fuse switches and low-voltage distribution equipment.
With a rated current of 50 A and a rated operating voltage of 690 V AC, the Mersen BTC69V50 is suitable for industrial control panels, switchboards, machinery and electrical distribution systems requiring reliable circuit protection at elevated operating voltages.

- Dependable BS88 gG full-range circuit protection.
- 50 A rated current for industrial electrical installations.
- 690 V AC voltage rating for demanding power systems.
- Protects cables and equipment against overloads and short circuits.
- Current-limiting operation helps reduce thermal and mechanical fault stress.
- Bolted-tag construction provides a secure electrical connection.
Key Features
- Mersen industrial BS88 fuse-link range.
- 50 A nominal current rating.
- 690 V AC rated operating voltage.
- gG utilisation category for full-range protection.
- Designed to protect cables, conductors and electrical equipment.
- Durable ceramic fuse body for industrial environments.
- Bolted-tag terminal configuration.
- Suitable for compatible fuse holders, fuse switches and switchgear.
Reliable Protection for Industrial Electrical Systems
The Mersen BTC69V50 operates by interrupting excessive current before it can cause serious damage to electrical cables, switchgear or connected equipment. During an overload or short circuit, the internal fuse element disconnects 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 it suitable for panel builders, electrical contractors and maintenance engineers working with industrial machinery, control panels and power distribution equipment.
Typical Applications
- Industrial electrical switchboards.
- Control panels and distribution boards.
- Low-voltage switchgear.
- Fuse switches and switch disconnectors.
- Industrial machinery and automation equipment.
- Cable, conductor and equipment protection.
