Why Choose the Mersen BTIA55V20 BS88 gG Fuse Link?
The Mersen BTIA55V20 is a compact and dependable British Standard BS88 gG fuse link designed to protect low-voltage 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 in industrial and commercial installations.
Its gG full-range operating characteristic enables the BTIA55V20 to interrupt sustained overloads as well as high-level short circuits. The durable ceramic body and offset-tag terminal configuration provide secure mechanical and electrical connections within compatible fuse holders, switch disconnectors and electrical distribution assemblies.
With a rated current of 20 A, a rated voltage of 550 V AC and a 250 V DC rating, the Mersen BTIA55V20 is suitable for control panels, switchboards, industrial machinery and general electrical distribution systems requiring reliable protection in a compact BS88 fuse-link format.

Reliable Protection for Electrical Distribution Systems
The Mersen BTIA55V20 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 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 the fuse suitable for panel builders, electrical contractors and maintenance engineers working with industrial machinery, control equipment and commercial power distribution systems.
Typical Applications
- Industrial control panels.
- Commercial electrical distribution boards.
- Low-voltage switchgear.
- Fuse switches and switch disconnectors.
- Industrial machinery and automation equipment.
- Cable, conductor and equipment protection.
