Product Description

The BUSSMANN MDA Series is a time-delay cylindrical fuse rated at 12 A and 250 V AC, with a non-indicating design and dimensions of 1/4 in x 1 1/4 in. This fuse is equivalent to the MDA and GSA series, identified by manufacturer part number MDA-12-R.

Frequently Asked Questions

What is the BUSSMANN MDA-12-R fuse used for?

The BUSSMANN MDA-12-R is a time-delay cylindrical fuse rated 12 A and 250 V AC, used for overcurrent protection in industrial control panels, motor circuits, and lighting systems. Its time-delay characteristic allows it to withstand temporary inrush currents without nuisance opening, making it suitable for applications with inductive loads.

What are the specifications of the BUSSMANN MDA-12-R fuse?

The BUSSMANN MDA-12-R is a 12 A, 250 V AC time-delay fuse from the MDA series. It has a non-indicating design and dimensions of 1/4 in x 1 1/4 in. The equivalent fuse series are MDA and GSA. The manufacturer part number is MDA-12-R, and it is a cylindrical, non-renewable fuse.

Where to buy the BUSSMANN MDA-12-R fuse worldwide?

3G Electric supplies the BUSSMANN MDA-12-R fuse worldwide. As a global industrial equipment distributor, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time. We source genuine BUSSMANN components for industrial applications.

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

To select the correct BUSSMANN MDA series fuse, verify the continuous current rating (e.g., 12 A for MDA-12-R) and voltage rating (250 V AC). Ensure the time-delay characteristic matches your circuit's inrush requirements. Confirm physical dimensions (1/4 in x 1 1/4 in) fit your fuse holder. Consult the BUSSMANN datasheet for interrupting capacity.
