Why Choose the Mersen BTCP69V63M100 Motor Protection Fuse Link?
The Mersen BTCP69V63M100 is a British Standard motor protection fuse link designed to provide dependable short-circuit protection for industrial motors, motor starters and associated control equipment. Its motor-rated operating characteristic allows the fuse to withstand temporary motor-starting currents while responding rapidly to severe electrical faults.
During a short circuit, the BTCP69V63M100 provides current-limiting operation that helps reduce the thermal and mechanical energy passed through to cables, contactors, switchgear and downstream components. This can minimise equipment damage, support effective protection coordination and reduce unplanned downtime within industrial motor-control systems.
With a 63M100 motor rating and a nominal voltage rating of 690 V AC, this Mersen fuse link is suitable for compatible industrial motor and power circuits. Its bolted-tag construction provides a secure electrical connection when installed in an appropriately rated fuse holder, fuse-switch or motor-control assembly.

Reliable Protection for Industrial Motor Circuits
Electric motors can draw several times their normal running current during start-up. A motor-rated fuse such as the Mersen BTCP69V63M100 is designed to tolerate this temporary inrush without unnecessary operation while still interrupting dangerous short-circuit currents quickly.
The fuse is normally used alongside a correctly selected overload relay or electronic motor protection device. The fuse provides high-level fault protection, while the overload device protects the motor against sustained overcurrent conditions. Selection should account for the motor current, starting method, starting duration, conductor capacity and prospective short-circuit current.
Typical Applications
- Industrial motor starter circuits.
- Motor control centres and control panels.
- Pumps, fans and ventilation systems.
- Conveyors and material-handling equipment.
- Compressors and production machinery.
- Fuse-switch and industrial power-distribution assemblies.
