Why Choose the Mersen BEIT42V40 BS88 Offset Bolted Tag Fuse-Link?
The Mersen BEIT42V40 is a 40 A BS88 industrial fuse-link designed to provide dependable overload and short-circuit protection for low-voltage electrical distribution systems. Its general-purpose fuse characteristic makes it suitable for protecting cables, feeders, switchgear and connected industrial equipment.
Featuring an offset bolted tag arrangement, the BEIT42V40 provides a secure mechanical and electrical connection within compatible fuse carriers, fuse-switch disconnectors and distribution equipment. This established British Standard format is widely used in industrial and commercial installations where reliable circuit isolation and straightforward fuse replacement are required.
With a rated current of 40 A, an AC voltage rating of 415 V and a DC voltage rating of 250 V, the Mersen BEIT42V40 is suitable for a broad range of power distribution and equipment protection applications. Its current-limiting performance helps reduce the thermal and mechanical stress caused by high prospective fault currents.
Key Advantages
- Reliable protection against overload and short-circuit currents.
- 40 A rated current for industrial and commercial circuits.
- Rated for operation at up to 415 V AC and 250 V DC.
- Current-limiting performance helps reduce damaging fault energy.

Reliable Protection for Electrical Distribution Circuits
The Mersen BEIT42V40 protects electrical installations by interrupting the circuit when excessive current exceeds the fuse-link’s operating limits. This helps prevent overheating, insulation damage and severe mechanical stress within cables, terminals and distribution equipment.
Its gG full-range operating characteristic provides protection against sustained overloads as well as high-level short-circuit currents. During a severe fault, the fuse-link limits the magnitude and duration of the current allowed to pass, helping to minimise damage to downstream equipment.
Correct fuse selection is essential. Any replacement must match the required current rating, voltage rating, utilisation category, breaking capacity, dimensions and bolted-tag configuration specified for the installation.
Typical Applications
- Industrial distribution boards.
- Commercial electrical installations.
- Cable and feeder protection.
- Fuse-switch disconnectors.
- Control panels and machinery.
- Heating and lighting circuits.
- Low-voltage switchgear assemblies.
- General industrial equipment protection.
