Product Description

The BUSSMANN MDQ Series Time-Delay Cylindrical Fuse (MPN MDQ-1/4) is a 250 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 without nuisance opening.

Frequently Asked Questions

What is the BUSSMANN MDQ-1/4 fuse used for?

The BUSSMANN MDQ-1/4 is a 250 mA, 250 V AC time-delay cylindrical fuse used in industrial control panels, HVAC equipment, and motor circuits where temporary inrush currents occur. Its time-delay characteristic prevents nuisance opening during startup surges while protecting downstream components from sustained overcurrent.

What are the specifications of the BUSSMANN MDQ-1/4 fuse?

The BUSSMANN MDQ-1/4 fuse is rated 250 mA at 250 V AC, with a time-delay response. It has a 1/4 in x 1 1/4 in cylindrical body and belongs to the MDQ series. The manufacturer part number is MDQ-1/4. This fuse is designed for applications requiring tolerance of temporary inrush currents.

Where to buy BUSSMANN MDQ-1/4 fuses worldwide?

3G Electric supplies BUSSMANN MDQ-1/4 fuses worldwide. As a global industrial solutions provider, we handle full logistics and customs clearance for international orders. Contact us to source this time-delay fuse for your application. We deliver to industrial facilities across all regions.

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

To select the correct BUSSMANN MDQ fuse, match the voltage rating (250 V AC) and current rating (250 mA) to your circuit requirements. Ensure the time-delay characteristic suits your inrush current profile. Verify the physical size (1/4 in x 1 1/4 in) fits your fuse holder. Consult a qualified engineer for critical applications.
