ATQ Time-Delay Midget Fuses

Mersen ATQ Time-Delay Midget Fuses feature a 500V_AC voltage rating with 42 ampere ratings from 1/10A to 30A. These fuses are ideal for the supplemental protection of circuits up to 30A where the available short circuit current does not exceed 10,000A. The ATQ fuses feature a 12-second time delay at a 200% rating for circuits with high inrush currents. Mersen ATQ Time-Delay Midget Fuses are suitable for lighting, solenoids, motors, and transformer circuits.
