Product Description

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

Frequently Asked Questions

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

The BUSSMANN MDQ-1/2 is a 500 mA, 250 V AC time-delay cylindrical fuse used in industrial control panels, HVAC equipment, and motor circuits. Its time-delay characteristic allows it to tolerate temporary inrush currents without nuisance opening, protecting sensitive components from sustained overloads.

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

The BUSSMANN MDQ-1/2 fuse is rated 500 mA at 250 V AC, with a physical size of 1/4 in x 1 1/4 in. It belongs to the MDQ Series and features a time-delay response. The manufacturer part number is MDQ-1/2, and it is designed for cylindrical fuse holders.

Where to buy BUSSMANN MDQ-1/2 fuses worldwide?

3G Electric supplies BUSSMANN MDQ-1/2 fuses worldwide. As a global industrial equipment distributor since 1990, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time; we source and deliver this fuse to any country.

How to select the correct BUSSMANN MDQ fuse for my application?

To select the correct BUSSMANN MDQ fuse, match the voltage rating (250 V AC) and current rating (500 mA for MDQ-1/2) to your circuit requirements. Ensure the physical size (1/4 in x 1 1/4 in) fits your fuse holder. The time-delay feature is ideal for circuits with motor starts or transformer inrush.
