Product Description

The BUSSMANN MDL Series Time-Delay Cylindrical Fuse (MPN MDL-1/2-R) is a 500 mA, 250 V AC fuse with a 1/4 in x 1 1/4 in size. This time-delay fuse is designed for applications requiring tolerance of temporary inrush currents.

Frequently Asked Questions

What is the BUSSMANN MDL-1/2-R fuse used for?

The BUSSMANN MDL-1/2-R is a 500 mA, 250 V AC time-delay cylindrical fuse used in industrial control panels, motor circuits, and power supplies where temporary inrush currents occur. Its time-delay characteristic prevents nuisance blowing during startup while protecting against sustained overloads and short circuits.

What are the specifications of the BUSSMANN MDL-1/2-R fuse?

The BUSSMANN MDL-1/2-R is a 500 mA, 250 V AC time-delay fuse from the MDL series. It has a cylindrical 1/4 in x 1 1/4 in body size. The manufacturer part number is MDL-1/2-R. It is designed for applications requiring tolerance of temporary inrush currents.

Where to buy BUSSMANN MDL-1/2-R fuses worldwide?

How to select the correct BUSSMANN MDL series fuse for my application?

Select the BUSSMANN MDL series fuse by matching the voltage rating (250 V AC), current rating (e.g., 500 mA for MDL-1/2-R), and time-delay characteristic to your circuit's normal operating current and inrush profile. Ensure the fuse's interrupting rating exceeds the available fault current. Consult the manufacturer's data sheet for specific application guidelines.
