Why Choose the Mersen BTIA69V20 BS88 gG Fuse Link?
The Mersen BTIA69V20 is a high-performance BS88 gG industrial fuse link designed to provide dependable protection for low-voltage electrical circuits against overloads and short circuits. Manufactured by Mersen, it helps safeguard cables, conductors, switchgear and connected equipment by safely interrupting excessive current during electrical fault conditions.
As part of Mersen’s industrial bolted-tag fuse-link range, the BTIA69V20 combines reliable fault interruption with effective current-limiting performance. Its full-range gG utilisation category enables the fuse to protect circuits against both sustained overload currents and high-level short circuits, making it suitable for general-purpose industrial distribution applications.
With a rated current of 20 A, an AC voltage rating of up to 690 V and a DC voltage rating of up to 460 V, the BTIA69V20 is suitable for industrial switchboards, control panels, machinery and feeder circuits. Its offset bolted-tag configuration provides a secure electrical and mechanical connection within compatible fuse holders and fused switching equipment.

Reliable Protection for Industrial Electrical Systems
The Mersen BTIA69V20 is designed to disconnect an electrical circuit when current rises beyond safe operating limits. Its gG characteristic provides full-range protection, covering prolonged overload conditions as well as high-level short circuits that could otherwise cause serious damage to conductors, switchgear and connected equipment.
During a fault, the fuse’s current-limiting action restricts the peak current and total electrical energy transferred through the circuit. Correct coordination with the associated fuse holder, switching device and downstream equipment can help reduce thermal and mechanical stress, improve system safety and minimise unplanned downtime.
Typical Applications
- Industrial power distribution systems.
- Electrical switchboards and control panels.
- Cable, conductor and feeder circuit protection.
- Industrial machinery and production equipment.
- Fuse switches and switch-disconnectors.
- Commercial and industrial electrical installations.
