Why Choose the Mersen A083651 Protistor High-Speed Fuse?
The Mersen A083651 is a high-performance Protistor semiconductor fuse designed to provide rapid and dependable protection for DC power equipment, semiconductor devices and railway electrical systems. Its high-speed operating characteristics help limit damaging fault energy before sensitive components are exposed to excessive thermal or electrical stress.
Part of Mersen's Protistor 36 × 127 mm gR range, the A083651 is developed for modern DC installations that demand low power losses, reduced pre-arcing I²t and reliable operation at elevated temperatures. These characteristics make it particularly suitable for protecting power conversion equipment and critical main or auxiliary circuits.
With a rated current of 80 A, a rated voltage of 1000 V DC and a cylindrical 36 × 127 mm body, the Mersen A083651 delivers effective full-range semiconductor protection. An integrated striker provides a mechanical indication or signalling function when the fuse operates.

Reliable High-Speed Protection for DC Power Systems
Power semiconductor devices can be damaged by short-duration fault currents before conventional industrial fuses operate. High-speed semiconductor fuses reduce the energy allowed through during a fault, helping protect rectifiers, converters, inverters and other sensitive power electronic components.
The Mersen A083651 is engineered for demanding DC installations where elevated operating temperatures, low power losses and rapid fault interruption are important. Its gR full-range characteristic provides protection against both overload and short-circuit conditions within correctly designed electrical systems.
Typical Applications
- Railway main and auxiliary power circuits.
- DC power conversion equipment.
- Rectifiers, inverters and converters.
- Industrial drive and traction systems.
- Battery and energy storage installations.
- Power semiconductor protection.
