Frequently Asked Questions

What is the BUSSMANN MDM-30 fuse used for?

The BUSSMANN MDM-30 is a time-delay cylindrical fuse used to protect electrical circuits from overcurrent in automotive, marine, and low-voltage industrial applications. Its 30 A rating at 32 V AC makes it suitable for power distribution and control panels where temporary inrush currents occur.

What are the specifications of the BUSSMANN MDM-30 fuse?

The BUSSMANN MDM-30 is a time-delay fuse rated for 30 A at 32 V AC. It has a physical size of 1/4 in x 1 1/4 in and belongs to the MDM series. The manufacturer part number is MDM-30. It is designed for cylindrical fuse holders and provides overcurrent protection with a delayed blow characteristic.

Where to buy the BUSSMANN MDM-30 fuse worldwide?

3G Electric supplies the BUSSMANN MDM-30 fuse to customers worldwide. As a global industrial solutions provider, we handle full logistics, customs clearance, and delivery to your location. Contact us for pricing and lead time on this BUSSMANN MDM series time-delay fuse.

How to select the correct BUSSMANN MDM-30 fuse for my application?

To select the correct BUSSMANN MDM-30 fuse, verify your circuit's continuous current does not exceed 30 A and the system voltage is 32 V AC or less. The time-delay characteristic handles motor or transformer inrush. Ensure the fuse holder accepts 1/4 in x 1 1/4 in cylindrical fuses. Consult a qualified engineer for critical applications.
