Cooper Bussmann MDL-1/8-R Cartridge Time Delay Fuse 0.13A

Product Description

The COOPER BUSSMANN MDL-1/8-R is a glass-body cartridge time delay fuse rated at 0.13 amps (A). Time delay fuses are designed to withstand brief inrush currents without nuisance opening, making them the correct choice for protecting small motors, transformers, and sensitive electronic circuits. The MDL-1/8-R measures 1.25 inches overall length with a 0.25 inch diameter, fitting standard mini fuse holders. With an interrupting rating of 10,000A at 125 volts and 35A at 250 volts, it provides reliable overcurrent protection within its rated application range. Licensed electricians and electronics technicians are the typical installers for this component class.

The MDL-1/8-R is suited for use in control panels, instrumentation, HVAC low-voltage circuits, and light industrial electrical equipment where a small-format, time delay cartridge fuse is specified. Its glass body allows visual inspection of the fuse element without removal, which speeds diagnostic work during troubleshooting. This fuse is sold individually but carries a minimum order quantity of 5 units, making it practical to stock as a service replacement item.

Installation Notes

Installation should be performed by a qualified electrician or electronics technician in accordance with applicable NEC requirements. Always de-energize and lock out the circuit before replacing a fuse. Confirm the replacement fuse amperage, voltage rating, and time delay characteristics match the original specification before installation. Never substitute a fuse with a higher amperage rating than the circuit is designed to carry.
