Value Collection BD7557 Cartridge Fast-acting Fuse 3A

Product Description

The VALUE COLLECTION BD7557 is a cartridge fast-acting fuse rated at 3 amps, designed for overcurrent protection in low-voltage electrical circuits. Built with a glass and ceramic body measuring 5/8 inches in overall length and 1/4 inch in diameter, this mini-style cartridge fuse responds quickly to fault conditions, interrupting the circuit before sustained overcurrent causes component damage. It is sold in a package quantity of 5. Electricians and electronics technicians typically install this type of fuse in control panels, instrumentation circuits, HVAC control boards, and other applications requiring fast, precise overcurrent response at low current thresholds.

This fuse is suited for residential and light commercial electrical and HVAC control circuits where a mini cartridge form factor is specified. The fast-acting timing makes it appropriate for circuits without high inrush loads, such as signal and control wiring, small transformer secondaries, and electronic component protection. Its compact 1/4 inch diameter and 5/8 inch length fit standard mini cartridge fuse holders common in control panels and equipment service boards.

Key Features

• Fast-acting fuse timing for rapid overcurrent interruption with no intentional delay
• 3 amp rating suitable for low-current control and signal circuit protection
• Mini cartridge body type fits standard 1/4 inch diameter fuse holders
• Glass and ceramic construction allows visual inspection of the fuse element
• Compact size: 5/8 inches overall length, 1/4 inch diameter
• Sold in a pack of 5 for servicing multiple units or keeping spares on hand

Compatibility

Designed as a standard mini cartridge fuse replacement for low-voltage control and signal circuits that specify a 3A fast-acting fuse in a 1/4 inch by 5/8 inch cartridge form factor.

Installation Notes

Installation should be performed by a qualified electrician or HVAC technician following applicable NEC guidelines. Always de-energize and lock out the circuit before removing or replacing a fuse. Confirm the replacement fuse matches the original amperage rating and form factor exactly — substituting a higher-rated fuse can defeat overcurrent protection and damage downstream components. Use an appropriate fuse puller tool when servicing fuse holders to avoid contact with live terminals.
