FERRAZ SHAWMUT's A100P300-4 Amp-Trap Form 101 semiconductor protection fuses are designed for high-voltage applications requiring superior reliability and fast-acting protection. These fuses feature low I²t to minimize damage to sensitive components during short circuits and controlled arc voltage to reduce stress on the circuit. They are commonly used in UPS systems, AC and DC drives, reduced voltage motor starters, and other semiconductor devices operating at voltages up to 1000V. The fuse’s fast-acting and current-limiting characteristics ensure rapid interruption of fault currents, safeguarding equipment and personnel.
