Why Choose the Mersen BTTM42V630 BS88 gG Fuse Link?
The Mersen BTTM42V630 is a heavy-duty BS88 gG industrial fuse link designed to protect high-current, low-voltage electrical circuits against overloads and short circuits. Manufactured by Mersen, it provides dependable fault interruption for cables, busbars, switchgear and connected equipment in demanding industrial and commercial power distribution systems.
As part of Mersen’s bolted-tag fuse-link range, the BTTM42V630 combines full-range circuit protection with effective current-limiting performance. Its gG utilisation category enables it to respond to sustained overload currents and high-level short circuits, helping to minimise the thermal and mechanical stresses placed on downstream electrical components.
With a rated current of 630 A and an operating voltage of up to 415 V AC, the BTTM42V630 is suitable for high-capacity switchboards, distribution panels, feeder circuits and industrial machinery supplies. Its robust bolted-tag construction provides a secure mechanical and electrical connection within compatible fuse holders, fuse switches and switch-disconnectors.

Reliable Protection for High-Current Electrical Systems
The Mersen BTTM42V630 is designed to disconnect an electrical circuit when current rises beyond safe operating limits. Its gG characteristic provides full-range protection, covering sustained overload conditions and high-level short circuits that could otherwise cause serious damage to conductors, busbars, switchgear and connected equipment.
During a serious electrical fault, the fuse limits the peak current and total energy passing through the circuit. Correct coordination with the associated fuse holder, switching device and downstream equipment can help reduce thermal and mechanical stress, improve installation safety and minimise costly equipment damage and unplanned downtime.
Typical Applications
- High-current industrial power distribution systems.
- Main electrical switchboards and distribution panels.
- Busbar, cable and feeder circuit protection.
- Industrial machinery and production equipment.
- Fuse switches and switch-disconnectors.
- Commercial and industrial electrical installations.
