Cooper Bussmann MDA-15-R Cartridge Time Delay Fuse 15A

Product Description

The COOPER BUSSMANN MDA-15-R is a mini cartridge time delay fuse rated at 15 amps and 250 volts. Built with a ceramic body, it provides reliable overcurrent protection in circuits where brief inrush currents are expected, such as those found in motors, transformers, and sensitive electronic equipment. The time delay characteristic allows normal startup surges to pass without nuisance blowing while still protecting against sustained fault conditions. At 1.25 inches overall length and 0.25 inches diameter, it fits standard mini cartridge fuse holders used in control panels, HVAC equipment, and industrial instrumentation. HVAC technicians, electricians, and service professionals install this fuse during routine maintenance and fault diagnosis.

This fuse is suited for low-voltage control circuits in residential and light commercial HVAC systems, electronic control boards, power supplies, and instrumentation panels where a time delay mini fuse is specified. It is commonly used wherever inrush current must be tolerated during equipment startup without sacrificing downstream circuit protection.

Key Features

• 15-amp rating with time delay characteristic for inrush-tolerant protection
• 250-volt AC rating suitable for low-voltage control and instrumentation circuits
• Ceramic body construction for thermal stability and arc containment
• Mini cartridge form factor: 1.25 inches OAL x 0.25 inches diameter
• UL Listed (Guide JDYX, File E19180) and CSA Class 1422-01 Certified
• RoHS compliant and tested to MIL-STD-202 Method 204

Compatibility

Designed as an OEM-style replacement mini cartridge time delay fuse for standard 0.25-inch diameter fuse holders rated for the MDA series form factor in HVAC control circuits, electronic panels, and industrial instrumentation equipment.

Installation Notes

Installation should be performed by a licensed electrician or qualified HVAC technician. De-energize and lock out the circuit before removing or replacing any fuse. Verify that the replacement fuse matches the original amperage, voltage, and time delay rating specified on the equipment nameplate or wiring diagram. Do not substitute a fast-acting fuse where a time delay type is required, as nuisance blowing or inadequate protection may result.
