Product Description

The BUSSMANN MDA Series is a time-delay cylindrical fuse rated at 20 A and 250 V AC, with a non-indicating design and dimensions of 1/4 in x 1 1/4 in. This fuse, identified by manufacturer part number MDA-20-R, is equivalent to the MDA and GSA series.

Frequently Asked Questions

What is the BUSSMANN MDA-20-R fuse used for?

The BUSSMANN MDA-20-R is a time-delay cylindrical fuse rated 20 A and 250 V AC. It protects industrial equipment, motors, and transformers from overloads and short circuits, allowing temporary inrush currents without nuisance tripping. Its non-indicating design suits applications where visual blown-fuse indication is not required.

What are the specifications of the BUSSMANN MDA-20-R fuse?

The BUSSMANN MDA-20-R is a time-delay, non-indicating cylindrical fuse rated 20 A and 250 V AC. It measures 1/4 in x 1 1/4 in and belongs to the MDA series, equivalent to the GSA series. The manufacturer part number is MDA-20-R. It is designed for overcurrent protection in industrial circuits.
