Twenty amps of fast-acting protection in a standard AGC glass-tube cartridge, this fuse opens quickly on an overload or short to protect the circuit and wiring downstream of it. The 1/4 inch by 1-1/4 inch glass body carries a visible internal element, so a technician can confirm at a glance whether it has blown without a meter. Fast-acting response suits electronic and lighting circuits.
Twenty amps of fast-acting protection in a standard glass-tube cartridge, this fuse opens quickly on an overload or short to protect the circuit and wiring downstream of it. The AGC size is the common 1/4 inch by 1-1/4 inch glass body, and the visible internal element makes it easy to confirm at a glance whether the fuse has blown.
Fast-acting means it clears a fault with little delay, which suits electronic and lighting circuits that need to drop offline the instant current climbs past the rating rather than riding through it. Reading the glass tube tells a technician a good fuse from a failed one without a meter.
Match the amperage and the voltage rating to the circuit being protected; a fuse rated too high defeats the purpose, and one rated too low nuisance-trips under normal load.
