Why Choose the Mersen BTIA69V40 Industrial Fuse Link?
The Mersen BTIA69V40 is a dependable British Standard industrial fuse link designed to provide overcurrent and short-circuit protection for electrical distribution, machinery and control applications. Manufactured by Mersen, it helps protect compatible cables, conductors, switchgear and connected equipment against potentially damaging fault currents.
The BTIA69V40 uses a current-limiting fuse element to disconnect the circuit when the current exceeds safe operating levels. Its rapid fault interruption helps reduce the thermal and mechanical stress applied to downstream components, supporting reliable operation and improved protection in demanding industrial electrical systems.
With a rated current of 40 A and a rated voltage of 690 V AC, the BTIA69V40 is suitable for compatible industrial power and control circuits. Its bolted-tag format provides a secure electrical connection when installed in a correctly rated fuse holder, switch-fuse assembly or distribution panel.

Reliable Protection for Industrial Electrical Systems
Industrial fuse links protect electrical installations by interrupting excessive current before it can cause serious overheating, insulation damage or equipment failure. During a short circuit or severe overcurrent condition, the internal fuse element operates rapidly to isolate the affected circuit and limit the energy passed through to downstream equipment.
The Mersen BTIA69V40 should be installed in a correctly rated and mechanically compatible fuse holder. Fuse selection should account for the operating voltage, continuous load current, prospective short-circuit current, conductor capacity and coordination with other protective devices in the installation.
Typical Applications
- Industrial electrical distribution panels.
- Machinery and production equipment.
- Automation and control panels.
- Switch-fuse and fuse-switch assemblies.
- Motor feeder and auxiliary power circuits.
- Cable, conductor and switchgear protection.
