Cooper Bussmann BP/MDL-1/2 Glass Tube Fuse 0.5A 250V 2 Pack

Product Description

The COOPER BUSSMANN BP/MDL-1/2 is a time-delay glass tube fuse rated at 0.5 amps and 250 volts, sold in a 2-pack carded format. MDL-type fuses use a slow-blow design that absorbs brief inrush currents without nuisance opening, making them well suited for electronic equipment and light-duty motor circuits. The glass tube body allows visual inspection of the element without a meter. At 0.1 pounds per pack, this is a compact, shelf-stable component for service vehicles and shop inventory. Electricians and electronics technicians keep MDL fuses on hand for routine protective-device replacement in control panels, instruments, and low-current circuits.

MDL-type time-delay fuses are commonly installed in electronic equipment, small appliances, instrumentation, and control circuits where a brief surge at startup must be tolerated without blowing the fuse. The 250-volt rating covers standard single-phase branch circuits and low-voltage control wiring. This 2-pack format is suited for service calls where a single replacement fuse is needed and a spare should remain on hand. Both residential and light commercial applications are typical for this fuse class.

Key Features

• Time-delay (slow-blow) design tolerates startup inrush without nuisance opens
• Glass tube body allows visual inspection of the fuse element
• Rated 0.5 amps at 250 volts for low-current electronic and control circuits
• MDL industry-standard form factor for broad fixture compatibility
• Carded 2-pack format keeps one spare immediately available

Compatibility

Designed as a standard MDL-type replacement fuse for electronic equipment, instrumentation, and control circuit fuse holders that accept a glass tube fuse of this amperage and voltage rating.

Installation Notes

MDL fuses are replaced by a licensed electrician or qualified technician. Always de-energize and lock out the equipment before opening any fuse holder or panel. Confirm the replacement fuse matches the amperage, voltage, and fuse type marked on the equipment nameplate or wiring diagram. Never substitute a higher-amperage fuse to resolve a repeated failure — diagnose the root cause of the overcurrent condition first.
