Why Choose the Mersen BTSDC42V63M100 BS88 gM Motor Fuse Link?
The Mersen BTSDC42V63M100 is a high-performance BS88 gM motor fuse link designed to provide dependable short-circuit protection for electric motors and associated industrial equipment. Manufactured by Mersen, it is engineered to tolerate the temporary inrush currents produced during motor starting while rapidly interrupting dangerous fault currents.
The BTSDC42V63M100 is suitable for coordinated motor protection systems incorporating contactors, motor starters and correctly selected overload relays. Its current-limiting operation helps reduce the peak current and fault energy passed to cables, switchgear and downstream components during a short circuit.
Featuring a 63 A continuous current rating, a 100 A motor circuit rating and an operating voltage of up to 415 V AC, this fuse link is suitable for demanding motor control and industrial automation applications. Its robust tagged construction supports secure installation in compatible BS88 fuse holders, fused switches and switch-disconnectors.

Reliable Short-Circuit Protection for Industrial Motors
Electric motors can draw several times their normal operating current while starting. The Mersen BTSDC42V63M100 is designed to withstand these temporary inrush currents while providing rapid interruption when a genuine short circuit occurs. This helps protect motor cables, contactors, starters and associated switchgear from damaging fault energy.
As a gM fuse link, the BTSDC42V63M100 is primarily intended to provide short-circuit protection rather than complete overload protection. It should therefore be coordinated with a suitable overload relay or motor protection device to provide comprehensive protection for the motor circuit.
Typical Applications
- Industrial motor starters.
- Motor control centres.
- Pumps, fans and compressor systems.
- Conveyors and material handling equipment.
- Manufacturing and processing machinery.
