Ferraz Shawmut A50QS800-4 AmpTrap Semiconductor Fuse

Ferraz Shawmut A50QS800-4 AmpTrap semiconductor fuse is a high-current protection device from Ferraz Shawmut’s AmpTrap line. It is rated for 800 A and 500 VAC, providing overcurrent protection for circuits that use semiconductor devices operating at voltages up to 500 VAC. The A50QS800-4 designation identifies this specific model within the AmpTrap family. This fuse is intended for use in demanding electrical systems where protection of power-electronic components is required, delivering robust fault-current interruption in high-current, high-voltage environments. Semiconductors and power electronics rely on such fuses to limit damage from overloads and short circuits, helping ensure safe operation of the connected equipment.
