Why Choose the Mersen BTM69V315 BS88 Centre Bolted Tag Fuse?
The Mersen BTM69V315 is a heavy-duty BS88 gG centre bolted tag fuse-link designed to protect industrial low-voltage electrical systems against overloads and short circuits. Its full-range fuse characteristic provides dependable protection for cables, switchgear, distribution equipment and other critical components in high-current power applications.
As part of the established Mersen BTM centre bolted tag fuse-link range, the BTM69V315 provides effective current-limiting performance to reduce the thermal and mechanical stresses produced by high fault currents. This helps minimise damage to connected equipment, improve electrical safety and support reliable operation in demanding industrial environments.
With a rated current of 315 A and voltage ratings of 690 V AC and 460 V DC, the BTM69V315 is suitable for industrial switchboards, power distribution panels, busbar systems and OEM electrical equipment. Its centre bolted tag configuration provides a secure electrical and mechanical connection within compatible BS88 fuse assemblies.

Reliable Protection for High-Current Electrical Systems
The Mersen BTM69V315 interrupts excessive current before cables, switchgear and connected equipment sustain serious damage. Its gG operating characteristic provides full-range protection against both sustained overload currents and high-level short circuits.
By limiting peak fault current and let-through energy, the fuse-link helps reduce stress on downstream electrical components. This supports improved system safety, reduced maintenance requirements and greater operational continuity across industrial power distribution installations.
Typical Applications
- Industrial switchboards and distribution boards.
- Main power distribution systems.
- Busbar and feeder circuit protection.
- Switch-fuse and fuse-disconnector assemblies.
- Industrial machinery and production equipment.
- OEM electrical panels and infrastructure systems.
