Why Choose the Mersen BTSDS42V63M80 BS88 Offset Tag Fuse-Link?
The Mersen BTSDS42V63M80 is a British Standard BS88 Type A3 offset tag fuse-link designed for general-purpose motor protection (gM) in low-voltage industrial electrical systems. Rated 63M80 A, it operates at up to 415 V AC and 240 V DC, providing dependable short-circuit protection for motor circuits while accommodating normal motor starting currents. It complies with EN 60269-2 Section II and BS88 Part 2.
The offset tag construction allows secure installation in compatible BS88 fuse holders, fuse-switch disconnectors and bolted busbar assemblies. Its gM operating characteristic offers excellent current limitation during fault conditions, helping protect motors, starters, contactors, cables and associated switchgear.

Reliable Protection for Motor Circuits
The Mersen BTSDS42V63M80 is engineered specifically for motor applications where temporary high inrush currents occur during starting. Its gM operating characteristic allows these normal transient currents while rapidly clearing high fault currents to minimise damage to motors, cables and associated equipment.
Its current-limiting design reduces thermal and mechanical stress during fault conditions, helping improve equipment reliability and minimise downtime in industrial installations.
Typical Applications
- Motor control centres.
- Industrial switchgear.
- Motor starters and contactor assemblies.
- Pumps and compressors.
- Conveyor systems.
- OEM machinery and automation equipment.
