Product Description

The BUSSMANN S506 Series is a time-delay cylindrical fuse rated at 63 mA and 250 V AC, with a 5 mm x 20 mm physical size. This S506-63-R model provides overcurrent protection for industrial equipment requiring a slow-blow response to temporary surges. Its compact cartridge design fits standard fuse holders in control panels and machinery.

Frequently Asked Questions

What is the BUSSMANN S506-63-R fuse used for?

The BUSSMANN S506-63-R is a time-delay cylindrical fuse used for overcurrent protection in industrial equipment that experiences temporary surge currents. It is commonly installed in control panels, machinery, and power supplies where a slow-blow response prevents nuisance tripping during startup.

What are the specifications of the BUSSMANN S506-63-R fuse?

The BUSSMANN S506-63-R is rated at 63 mA and 250 V AC, with a time-delay characteristic. It has a 5 mm x 20 mm cylindrical cartridge size and belongs to the S506 series. This compact design fits standard fuse holders in industrial control panels.

Where to buy the BUSSMANN S506-63-R fuse worldwide?

You can source the BUSSMANN S506-63-R fuse worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on this BUSSMANN fuse.

How to select the correct BUSSMANN S506 series fuse for my application?

To select the correct BUSSMANN S506 series fuse, verify your circuit's operating voltage (250 V AC maximum) and normal current draw. Choose a time-delay fuse rated slightly above the normal current to handle inrush surges. Ensure the 5 mm x 20 mm cartridge fits your fuse holder.
