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

Product Description

The COOPER BUSSMANN MDL-15-R is a glass-body cartridge time delay fuse rated at 15 amps. It measures 1.25 inches overall length with a 0.25 inch diameter, making it a compact mini-style fuse suited for low-current protection applications. The time delay characteristic allows brief inrush current spikes to pass without nuisance opening, while still protecting against sustained overloads and short circuits. This fuse is installed by licensed electricians and qualified HVAC or electronics technicians in control circuits, instrumentation panels, and low-voltage equipment where a fast-blow fuse would cause unnecessary interruptions.

The MDL-15-R is commonly used in residential and light commercial control boards, HVAC equipment, and electronic instrumentation. Its mini cartridge form factor fits standard fuse holders designed for 0.25 inch diameter cylindrical fuses. This fuse is appropriate for applications requiring CE, UL, CSA, and RoHS-compliant overcurrent protection components in both new installations and service replacement work.

Compatibility

Designed as an OEM-style replacement for mini cartridge fuse holders accepting 0.25 inch diameter, 1.25 inch overall length cylindrical fuses rated at 15 amps with a time delay characteristic.

Installation Notes

Installation should be performed by a qualified electrician or licensed technician. Always de-energize and lock out the circuit before replacing a fuse. Confirm the replacement fuse matches the original amperage rating, voltage rating, and time delay classification. Do not substitute a fast-blow fuse in a circuit designed for time delay protection, as nuisance tripping or equipment damage may result.
