Frequently Asked Questions

What is a BUSSMANN FRS-R-50 fuse used for?

The BUSSMANN FRS-R-50 is a Class RK5 time-delay fuse rated 50 A, 600 V AC / 250 V DC. It protects motors, transformers, and other inductive loads from short circuits and sustained overloads. Its time-delay characteristic prevents nuisance opening during inrush currents, making it ideal for industrial control panels and power distribution.

What are the specifications of the BUSSMANN FRS-R-50 fuse?

The BUSSMANN FRS-R-50 is a non-indicating, time-delay cylindrical fuse from the FRS-R series. It carries a 50 A rating, 600 V AC and 250 V DC, with a Class RK5 rejection feature. The manufacturer part number is FRS-R-50. It is designed for branch-circuit protection in industrial equipment.

Where to buy BUSSMANN FRS-R-50 fuses worldwide?

3G Electric supplies BUSSMANN FRS-R-50 fuses to customers worldwide. As a global industrial sourcing partner, we handle full logistics, customs clearance, and delivery to your site. Contact us for a quote on the FRS-R-50 or other BUSSMANN fuse series. We provide genuine BUSSMANN components for industrial applications.

How to select the right BUSSMANN FRS-R fuse for an application?

To select the correct BUSSMANN FRS-R fuse, match the voltage rating (600 V AC or 250 V DC) and current rating (e.g., 50 A) to your circuit requirements. Verify the Class RK5 rejection feature fits your fuse holder. For motor circuits, ensure the time-delay characteristic accommodates starting inrush. Consult a qualified engineer for branch-circuit coordination.
