Why Choose the Mersen BTIA55V4 Industrial Fuse Link?
The Mersen BTIA55V4 is a compact British Standard industrial fuse link designed to provide dependable overcurrent and short-circuit protection for low-current electrical circuits. Manufactured by Mersen, it helps protect cables, control equipment and connected components against excessive current and potentially damaging electrical faults.
The BTIA55V4 uses a current-limiting fuse element to disconnect the circuit when the current exceeds safe operating levels. Rapid fault interruption helps reduce the thermal and mechanical stress placed on conductors, switchgear and downstream equipment, supporting reliable operation in industrial and commercial electrical installations.
With a rated current of 4 A and a rated voltage of 550 V AC, the BTIA55V4 is suitable for compatible control, auxiliary and distribution circuits. Its bolted-tag construction provides a secure electrical connection when installed in an appropriately rated fuse holder or switch-fuse assembly.

Reliable Protection for Control and Auxiliary Circuits
Industrial fuse links protect electrical systems by interrupting excessive current before it can cause serious overheating or equipment damage. During a short circuit or severe overcurrent condition, the internal fuse element operates and safely disconnects the affected circuit.
The Mersen BTIA55V4 should be installed in a correctly rated and mechanically compatible fuse holder. Fuse selection should consider the circuit voltage, normal load current, prospective short-circuit current, conductor capacity and coordination with other protective devices.
Typical Applications
- Industrial control and auxiliary circuits.
- Electrical control panels and switchboards.
- Instrumentation and monitoring equipment.
- Machinery control systems.
- Low-current distribution circuits.
- Maintenance and replacement of industrial fuse links.
