Frequently Asked Questions

What is the BUSSMANN S505-5-R fuse used for?

The BUSSMANN S505-5-R is a time-delay cylindrical fuse used for overcurrent protection in industrial control panels, power supplies, and lighting circuits. Its 5 A, 250 V AC rating and 5 mm x 20 mm size make it suitable for applications requiring inrush tolerance, such as motor starters and transformers.

What are the specifications of the BUSSMANN S505-5-R fuse?

The BUSSMANN S505-5-R is a 5 A, 250 V AC time-delay fuse from the S505 series. It is non-indicating, measures 5 mm x 20 mm, and is equivalent to the S505, 477, and GSF series. The manufacturer part number is S505-5-R. It provides reliable overcurrent protection with a slow-blow characteristic.

Where to buy BUSSMANN S505-5-R fuses worldwide?

You can source BUSSMANN S505-5-R fuses 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 times. 3G Electric supplies genuine BUSSMANN components for industrial applications.

How to select the correct BUSSMANN S505-5-R fuse for an application?

To select the BUSSMANN S505-5-R, verify your circuit's voltage (250 V AC max) and continuous current (5 A). Ensure the 5 mm x 20 mm cartridge fits your holder. The time-delay characteristic is ideal for loads with high inrush current, such as capacitors or motors. Always consult the manufacturer's data sheet for coordination.
