Cooper Bussmann MDL-10-R Cartridge Time Delay Fuse 10A

Product Description

The COOPER BUSSMANN MDL-10-R is a glass-body cartridge time delay fuse rated at 10 amps. Built in the mini cartridge form factor, it measures 1.25 inches in overall length and 0.25 inches in diameter. The time delay characteristic allows brief inrush currents to pass without nuisance opening, making it well suited for small motors, transformers, and sensitive electronics where a fast-blow fuse would trip prematurely. Licensed electricians and electronics technicians install this type of fuse in control panels, instrumentation circuits, and low-current branch circuits. It carries CE, CSA, UL 248-14, and RoHS certifications, confirming compliance with both North American and international standards.

The MDL-10-R is used in residential and light commercial control circuit applications where a compact, reliable overcurrent protective device is required. Typical installations include HVAC control boards, small appliance panels, and instrumentation enclosures that require a time delay fuse in a 1/4-inch diameter glass cartridge body. The mini form factor fits standard fuse holders and blocks designed for the 1/4 inches by 1-1/4 inches cartridge size.

Key Features

• 10-amp time delay rating handles short-duration inrush currents without nuisance tripping
• Glass cartridge body allows visual inspection of the fuse element without tools
• Mini cartridge form factor: 1.25 inches OAL x 0.25 inches diameter
• RoHS compliant construction meets international hazardous-substance restrictions
• UL 248-14 recognized and CSA Component Accepted for North American installations
• MIL-STD-202 tested for vibration and high-shock environments

Compatibility

Designed as an OEM-style replacement for standard 1/4-inch by 1-1/4-inch mini cartridge fuse holders and fuse blocks rated for time delay, 10-amp glass cartridge fuses.

Installation Notes

Installation and replacement of branch-circuit fuses must be performed by a qualified electrician in accordance with NEC requirements. Always de-energize and lock out the circuit before removing or inserting a fuse. Verify that the replacement fuse matches the amperage, voltage, and time delay rating specified by the equipment manufacturer. Never substitute a higher-amperage fuse or bypass the fuse holder.
