Cooper Bussmann MDL-6-1/4-R Time Delay Fuse 6.25A

Product Description

The COOPER BUSSMANN MDL-6-1/4-R is a cartridge-style, time delay fuse rated at 6.25 amps and designed for low-current circuit protection in control panels, instrumentation, and light-duty electrical equipment. The glass body measures 1.25 inches in overall length and 0.25 inches in diameter, conforming to the standard miniature cartridge fuse form factor. Time delay action allows brief inrush current events to pass without nuisance tripping, while still protecting against sustained overloads and fault conditions. Electricians and electronics technicians install this fuse in fuse holders and blocks rated for the miniature cartridge size.

This fuse is suited for residential and commercial control circuits, small appliance protection, instrumentation panels, and low-voltage equipment where a slow-blow fuse characteristic is required. The glass body allows visual inspection of the fuse element without removal, simplifying field troubleshooting. The compact miniature form factor fits standard 0.25-inch-diameter cartridge fuse holders commonly found in control boards and panel-mounted fuse blocks across HVAC, electrical, and light industrial applications.

Key Features

• Time delay (slow-blow) action tolerates brief inrush currents without nuisance tripping
• Glass body enables quick visual inspection of the fuse element in the field
• High interrupting rating: 10,000 amps at 125 volts and 200 amps at 250 volts
• Meets UL 248-14, CSA Class 1422-01, CE, RoHS, and MIL-STD-202 standards
• Compact miniature cartridge profile fits standard 0.25-inch fuse holders
• RoHS-compliant construction for use in environmentally regulated applications

Compatibility

Designed as an OEM-style replacement for miniature cartridge fuse positions requiring a 6.25-amp, time delay, 0.25-inch-diameter by 1.25-inch-long glass fuse.

Installation Notes

Installation should be performed by a qualified electrician or electronics technician. Always de-energize and lock out the circuit before replacing a fuse. Confirm the replacement fuse matches the amperage, voltage, timing, and physical dimensions of the original before inserting it into the fuse holder. Do not install a fuse with a higher amperage rating than the circuit is designed for, as this defeats overcurrent protection.
