Why Choose the Mersen BTSDC42V63M80 BS88 gM Motor Fuse Link?
The Mersen BTSDC42V63M80 is an industrial BS88 motor circuit fuse link designed to provide dependable short-circuit protection for motors, starters and associated electrical equipment. Manufactured by Mersen, this fuse is suitable for control panels, motor control centres, switchgear and OEM machinery requiring reliable protection against high fault currents.
Its gM motor-circuit characteristic is intended to tolerate the temporary inrush currents associated with motor starting while rapidly interrupting damaging short-circuit currents. Overload protection is normally provided by a correctly selected motor overload relay, thermal protection device or electronic motor protection unit.
The 63M80 designation indicates a motor fuse with a 63 A conventional current reference and performance suited to motor circuits associated with an 80 A rating. The product code also identifies a nominal 415 V AC voltage class. Final selection should be verified against the applicable Mersen technical documentation and the requirements of the protected motor circuit.
Key Advantages
- Designed specifically for motor circuit short-circuit protection.
- Allows normal motor starting currents to pass without unnecessary operation.
- 63M80 motor fuse designation for coordinated motor protection.
- 415 V AC nominal voltage class.
- Current-limiting operation helps reduce peak fault current and let-through energy.
- Suitable for industrial motor control panels and switchgear assemblies.
Key Features

Reliable Protection for Industrial Motor Circuits
Electric motors can draw several times their normal operating current during starting. A gM fuse is designed to withstand this temporary inrush while providing rapid interruption when a serious short-circuit fault occurs. This helps protect cables, contactors, starters and other components from excessive thermal and mechanical stress.
The Mersen BTSDC42V63M80 should be installed as part of a coordinated motor protection system. The fuse provides short-circuit protection, while a separate overload device protects the motor against sustained overcurrent, phase loss and other abnormal operating conditions.
Typical Applications
- Industrial motor control centres.
- Direct-on-line and star-delta motor starters.
- Pumps, fans and compressor systems.
- Conveyors and materials-handling equipment.
- Manufacturing and processing machinery.
- OEM control panels and switchgear assemblies.
