Cooper Bussmann MDQ-1-1/2 Time Delay Fuse 1.5A Mini

Product Description

The COOPER BUSSMANN MDQ-1-1/2 is a miniature cartridge time-delay fuse rated at 1.5 amps. It features a glass body with two elements and measures 1.25 inches in overall length with a 0.25 inch diameter. The time-delay design allows brief inrush currents to pass without nuisance tripping while still providing reliable overcurrent protection. Licensed electricians and instrumentation technicians install this fuse type in low-current control circuits, instrumentation panels, and light-duty electronic equipment where precise amperage protection is required.

This fuse is suited for residential and commercial control circuit applications where a compact mini form factor is necessary. The glass body allows visual inspection of the fuse element without removal, simplifying fault diagnosis during service calls. It is commonly found in HVAC control boards, small appliances, and electronic control panels where 1.5 amp time-delay protection is specified by the equipment manufacturer.

Key Features

• Time-delay action tolerates short-duration inrush currents without nuisance opens
• Mini cartridge form factor at 1.25 inches OAL and 0.25 inch diameter
• Glass body enables quick visual inspection of the fuse element
• Dual-element construction provides both overload and short-circuit protection
• UL Listed 248-14 and CSA Class 1422-01 Component Accepted

Compatibility

Designed as a direct replacement for mini cartridge time-delay fuses rated at 1.5 amps with a 1.25 inch OAL and 0.25 inch diameter in standard mini fuse holders and control panels.

Installation Notes

Installation should be performed by a licensed electrician or qualified technician. De-energize and lock out the circuit before replacing any fuse. Verify the replacement fuse amperage and time-delay rating match the equipment manufacturer specifications exactly. Never substitute a higher-amperage or fast-acting fuse where a time-delay type is required.
