Value Collection BD7550 Cartridge Fast-acting Fuse 4A 5-pack

Product Description

The VALUE COLLECTION BD7550 is a mini cartridge fast-acting fuse rated at 4 amps, designed for overcurrent protection in low-current electrical circuits. The fuse body is constructed from glass, allowing visual inspection of the element without removal. At 5/8 inch overall length and 1/4 inch diameter, this is a standard mini cartridge form factor suited for fuse holders and panels that accept this size. Fast-acting response means the element opens quickly on overload, protecting sensitive downstream components. Electricians and electronics technicians install these in control panels, instrumentation, and low-voltage circuit protection applications.

This fuse is appropriate for residential and light commercial electrical control circuits where fast-acting overcurrent protection is required in a mini cartridge form. The glass body construction makes it straightforward to verify element integrity during inspection or troubleshooting. This listing is sold as a pack of 5 units, providing spares for service kits or panel restocking. Typical installation environments include HVAC control boards, instrumentation panels, and other equipment requiring 4-amp fast-acting protection in the mini cartridge footprint.

Key Features

• Fast-acting fuse timing for rapid overcurrent response to protect sensitive circuit components
• Glass body construction allows visual element inspection without a continuity tester
• Mini cartridge form factor: 5/8 inch OAL x 1/4 inch diameter
• 4-amp rating suitable for low-current control circuit protection
• Sold in a 5-pack for service kit stocking or panel maintenance

Compatibility

Designed as an OEM-style replacement for mini cartridge fuse holders accepting a 1/4 inch diameter by 5/8 inch fast-acting glass fuse rated at 4 amps.

Installation Notes

Installation is performed by a qualified electrician or service technician. Always de-energize and lock out the circuit before replacing a fuse. Verify the replacement fuse amperage matches the circuit protection requirement exactly — never substitute a higher-rated fuse. Confirm the fuse holder is rated for the cartridge dimensions before insertion.
