Frequently Asked Questions

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

The BUSSMANN ABC-20-R is a fast-acting cylindrical fuse rated 20 A and 250 V AC. It protects sensitive electronic circuits and equipment from overcurrent by quickly interrupting the circuit during a fault. Common applications include control panels, power supplies, and industrial machinery where rapid response to short circuits is required.

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

The BUSSMANN ABC-20-R is a fast-acting, non-indicating fuse from the ABC series. It is rated 20 A at 250 V AC, with dimensions of 1/4 in x 1 1/4 in. It is equivalent to the ABC and GAB series. The manufacturer part number is ABC-20-R, and it is designed for overcurrent protection in industrial equipment.

Where to buy the BUSSMANN ABC-20-R fuse worldwide?
