Cooper Bussmann MDA-2-R Cartridge Time Delay Fuse 2A

Product Description

The COOPER BUSSMANN MDA-2-R is a ceramic cartridge time delay fuse rated at 2 amps and 250 volts. It belongs to the mini fuse form factor, measuring 1.25 inches in overall length and 0.25 inches in diameter. The time delay design allows brief inrush currents to pass without nuisance tripping while still providing reliable overcurrent protection. This fuse is suited for electronic control boards, instrumentation panels, and low-voltage circuits where small-format overcurrent protection is required. Licensed electricians, HVAC technicians, and electronics service professionals are the primary installers.

The MDA-2-R is used in residential and light commercial applications where a mini cartridge fuse is specified on a control board or panel. Common install scenarios include HVAC control circuits, appliance protection circuits, and electronic equipment requiring a 2-amp time delay fuse in the standard 0.25 inch by 1.25 inch body size. Always verify the required amperage and voltage rating against the equipment nameplate or schematic before replacement.

Key Features

• 2-amp time delay rating allows short-duration inrush currents without nuisance opens
• 250-volt AC rating covers most residential and light commercial control circuit applications
• Ceramic fuse body provides thermal stability and arc suppression
• Mini cartridge form factor: 1.25 inches OAL by 0.25 inches diameter
• CSA Class 1422-01 Certified and UL Listed (Guide JDYX, File E19180)
• RoHS compliant and tested to MIL-STD-202 Method 204

Compatibility

Designed as a direct replacement for mini cartridge fuse holders accepting a 0.25 inch by 1.25 inch time delay fuse rated at 2 amps and 250 volts. Verify fuse holder type and circuit ratings before installation.

Installation Notes

De-energize and lock out the circuit before replacing any fuse. Confirm the replacement fuse matches the amperage, voltage, and timing characteristics specified on the equipment schematic or control board label. Use a dedicated fuse puller for mini cartridge fuses to avoid damaging the fuse holder clips. Never substitute a higher-amperage fuse or bypass the fuse holder.
