Why Choose the Mersen V076470 45ASB36V63P-1 High Voltage Motor Fuse?
The Mersen V076470 is a high-performance Limitor® aSJB/D high voltage back-up fuse developed specifically for the protection of medium and high voltage motors. Also identified by the catalogue number 45ASB36V63P-1, it helps protect motors, switchgear and associated electrical equipment against damaging short-circuit currents.
Motor circuits experience repeated current peaks during starting, making a purpose-designed fuse essential for dependable protection. The V076470 is engineered to withstand normal motor-starting currents while operating rapidly when a serious fault occurs. Its robust construction uses silver-plated copper fuse elements, silver-plated brass end caps and a durable melamine fibreglass body.
With a rated voltage of 3.6 kV AC, a rated current of 63 A and an integrated 20 N striker, this fuse is suitable for industrial motor control systems and high voltage switchgear. Its compact 50.8 mm diameter by 192 mm length format supports straightforward integration into compatible fuse bases and protection assemblies.

Reliable Protection for High Voltage Motors
High voltage motor fuses must distinguish between normal motor-starting currents and damaging short-circuit conditions. The Mersen V076470 is designed to tolerate repeated starting peaks while providing reliable back-up protection when fault currents exceed safe operating levels.
The integrated striker can interact with compatible switchgear to provide fuse operation indication or initiate a mechanical tripping function. This supports safer fault isolation and helps minimise damage to motors, contactors and other equipment within the electrical system.
Typical Applications
- Medium and high voltage motor protection.
- Industrial motor control centres.
- Pumps, compressors and ventilation motors.
- Processing and manufacturing machinery.
- High voltage switchgear and controlgear.
- Industrial power distribution systems.
