Why Choose the Mersen ATQ3/10 Time-Delay Fuse?
The Mersen ATQ3/10 is a precision-engineered 0.3 A time-delay midget fuse designed to provide dependable supplementary overcurrent protection for industrial control circuits and sensitive electrical equipment. As part of the trusted Mersen Amp-Trap® ATQ series, it is ideal for protecting transformers, relays, solenoids and other inductive loads that experience temporary inrush currents during normal operation.
Its time-delay characteristic allows the fuse to withstand brief start-up current surges without nuisance operation while providing reliable protection against sustained overloads and short-circuit faults. This helps improve equipment reliability while reducing unnecessary maintenance and downtime.
Rated at 0.3 A with a maximum operating voltage of 500 V AC, the ATQ3/10 features the industry-standard 10 × 38 mm midget fuse format for straightforward installation into compatible fuse holders used in industrial control panels and automation equipment.
