Mersen A089470 Protistor high-speed cylindrical semiconductor fuse rated at 8 A and 1500 V DC, with a 20 x 190 mm gR design and 60 kA breaking capacity.
£87.98
The Mersen A089470 is a high-performance DC semiconductor fuse designed to protect sensitive power electronic equipment against damaging overload and short-circuit currents. Part of Mersen's advanced Protistor 20 × 190 mm fuse range, it provides rapid fault interruption for railway, industrial and power conversion systems.
The A089470 is engineered for modern DC equipment operating at elevated voltages and temperatures. Its low pre-arcing I²t helps reduce the electrical and thermal energy passed to protected components during a fault, while its low power losses contribute to efficient operation and an extended service life.
With a rated current of 8 A, a rated voltage of 1500 V DC and a cylindrical 20 × 190 mm format, the Mersen A089470 is ideal for protecting semiconductor devices in railway power circuits, auxiliary systems, converters and other high-voltage DC applications.
Power semiconductor devices can be damaged by extremely short overcurrent events. High-speed fuses interrupt these faults rapidly and limit the energy passed into connected equipment, helping protect converters, rectifiers, traction systems and other valuable power electronic components.
The Mersen A089470 is specifically developed for new-generation DC equipment that may operate at higher temperatures than conventional electrical systems. Its combination of low I²t, low watt losses and high breaking capacity makes it a reliable protection solution for demanding industrial and railway installations.
