Why Choose the Mersen BTIA69V50 Industrial Fuse Link?
The Mersen BTIA69V50 is a British Standard industrial fuse link designed to provide dependable overcurrent and short-circuit protection for electrical distribution, machinery and control applications. It helps protect compatible cables, conductors, switchgear and connected equipment against potentially damaging fault currents.
During an electrical fault, the BTIA69V50 interrupts excessive current to help limit the thermal and mechanical energy passed through to downstream components. This current-limiting operation can reduce equipment damage, support effective protection coordination and improve the reliability of industrial electrical installations.
With a rated current of 50 A and a nominal voltage rating of 690 V AC, the BTIA69V50 is suitable for compatible industrial power and distribution circuits. Its bolted-tag construction provides a secure electrical connection when installed in a correctly rated fuse holder, fuse-switch or switch-fuse assembly.

Reliable Protection for Industrial Electrical Systems
Industrial fuse links protect electrical installations by disconnecting excessive current before it can cause serious conductor overheating, insulation damage or equipment failure. During an overload or short-circuit condition, the internal fuse element operates to isolate the affected circuit and limit the electrical energy reaching downstream equipment.
The Mersen BTIA69V50 should be installed in a correctly rated and mechanically compatible fuse holder. Selection should account for the circuit voltage, normal load current, prospective short-circuit current, conductor capacity, operating conditions and coordination with other protective devices.
Typical Applications
- Industrial electrical distribution panels.
- Machinery and production equipment.
- Automation and control systems.
- Switch-fuse and fuse-switch assemblies.
- Power supply and feeder circuits.
- Cable, conductor and switchgear protection.
