Cooper Bussmann BP/MAS-3A Mini Light Set Fuse 3A 5 Pack

Product Description

The COOPER BUSSMANN BP/MAS-3A is a 3-amp, 125-volt replacement fuse for holiday mini light sets, sold in a 5-pack. These fast-acting fuses protect low-voltage decorative light strings from overcurrent faults. Each fuse measures 0.95 inches long, 0.55 inches wide, and 0.076 inches in height. The compact form factor is designed to fit the fuse compartments built into the plugs of standard mini light strands. Electricians and electrical-savvy installers keep these on hand during the holiday season and throughout the year for general decorative lighting maintenance.

Rated for both indoor and outdoor use, the BP/MAS-3A is suitable for residential and light commercial decorative lighting applications. The 3A rating covers the typical current draw of standard mini light sets. The multi-purpose design supports year-round usage beyond holiday lighting, including other low-voltage decorative string light applications that use the same fuse format. Having a 5-pack on hand reduces downtime when a fuse opens during normal operation.

Installation Notes

Always disconnect the light set from the power source before replacing the fuse. Open the fuse compartment on the plug using a small flathead screwdriver, remove the blown fuse, and insert the replacement. Do not substitute a higher-amperage fuse, as this will defeat overcurrent protection. Work on decorative lighting should follow applicable NEC guidelines for low-voltage decorative lighting installations.
