Value Collection BD-7543-1 Cartridge Fast-acting Fuse 20A

Product Description

The VALUE COLLECTION BD-7543-1 is a mini cartridge fast-acting fuse rated at 20 amps, designed for overcurrent protection in low-voltage electrical circuits and control systems. The glass body measures 7/8 inches in overall length and 1/4 inch in diameter, providing a compact form factor suited for fuse holders and panel boards that accept standard mini cartridge sizes. Fast-acting response means the fuse clears fault current quickly, limiting damage to downstream components. Electricians and control technicians install this fuse type in branch circuit protection, equipment control panels, and secondary circuit applications where rapid interruption is required.

This fuse is appropriate for residential and light commercial electrical applications, instrumentation panels, and HVAC control board fuse positions that accept mini cartridge fuses in the 1/4 inch by 7/8 inch form factor. It is commonly used in low-voltage circuits where a fast-blow characteristic is necessary to protect sensitive electronics or wiring from sustained overcurrent conditions. Each package contains 5 fuses, making it practical for service technicians stocking replacement inventory on the truck or in the shop.

Key Features

• 20 amp fast-acting rating for rapid overcurrent interruption
• Mini cartridge body style fits standard 1/4 inch by 7/8 inch fuse holders

• Sold in a 5-piece package for convenient service stock replenishment

Compatibility

Designed as a replacement for mini cartridge fuse positions accepting a 1/4 inch diameter by 7/8 inch overall length fast-acting fuse rated at 20 amps. Verify fuse holder dimensions, amperage rating, and interrupting rating requirements before installation.

Installation Notes

Fuse replacement should be performed by a qualified electrician or licensed technician. De-energize and lock out the circuit before removing or installing any fuse. Confirm that the replacement fuse amperage and interrupting rating meet or exceed the requirements specified on the equipment nameplate or wiring diagram. Never substitute a fuse with a higher amperage rating than the circuit or equipment is designed for.
