Why Choose the Mersen BTKF42V315 Industrial Fuse-Link?
The Mersen BTKF42V315 is a heavy-duty 315 A industrial fuse-link designed to provide dependable overcurrent and short-circuit protection in low-voltage power distribution systems. Its high-current capacity makes it suitable for demanding commercial and industrial installations where cables, switchgear and connected equipment require reliable fault protection.
The fuse-link disconnects the protected circuit when current exceeds its designed operating limits, helping to reduce the thermal and mechanical stress caused by electrical faults. Its current-limiting action can also minimise damage to downstream equipment and support effective coordination within the wider protection system.
With a 315 A rated current and a 415 V AC voltage designation, the Mersen BTKF42V315 is suitable for compatible distribution boards, fuse-switch disconnectors, switchgear assemblies and industrial power systems. The fuse-link’s physical dimensions, tag arrangement and operating class should always be checked against the installed fuse carrier before replacement.

Reliable Protection for High-Current Distribution Systems
High-current electrical faults can expose cables, busbars and switchgear to severe thermal and mechanical forces. The Mersen BTKF42V315 is designed to interrupt excessive current and isolate the affected circuit before fault energy causes extensive equipment damage.
For safe and effective protection, the fuse-link must be coordinated with the circuit conductors, connected equipment and upstream or downstream protective devices. Replacement should only be carried out after the cause of operation has been identified and the circuit has been made safe.
Typical Applications
- Industrial power distribution systems.
- Main and sub-main feeder protection.
- Commercial distribution boards.
- Fuse-switch disconnectors.
- Industrial switchgear assemblies.
- Cable and busbar protection.
- Machinery and production facilities.
