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

Product Description

The COOPER BUSSMANN MDL-2-R is a glass cartridge time delay fuse rated at 2 amps. It measures 1.25 inches overall length and 0.25 inches in diameter, making it a standard mini cartridge form factor. The time delay characteristic allows it to handle brief inrush currents without nuisance tripping, while still providing reliable overcurrent protection. Interrupting ratings are 100 amps at 250 volts and 10,000 amps at 125 volts. Licensed electricians and electronics technicians install this fuse in control circuits, instrumentation panels, and low-current electrical equipment where short-time overload tolerance is required.

This fuse is suited for residential and light commercial control panel applications, instrumentation enclosures, and electronic equipment requiring low-amperage overcurrent protection. Its mini cartridge form fits standard fuse holders designed for 0.25-inch diameter cartridge fuses. The time delay design is appropriate for circuits with motors or transformers that draw higher startup current before settling to steady-state load.

Compatibility

Designed as an OEM-style replacement for mini cartridge fuse holders accepting 0.25-inch diameter, 1.25-inch overall length time delay fuses in control and instrumentation applications.

Installation Notes

Installation should be performed by a licensed electrician following applicable NEC requirements. De-energize and lock out the circuit before removing or replacing any fuse. Verify the replacement fuse amperage and voltage rating match the original equipment specification before installing. Do not substitute a fast-acting fuse for a time delay fuse or exceed the rated amperage of the original fuse.
