Product Description

The BUSSMANN FRS-R-20ID is a Class RK5, time-delay cylindrical fuse from the FRS-R-ID Series, rated at 20 A, 600 V AC and 300 V DC. Its indicating feature provides visual confirmation of operation, supporting maintenance and troubleshooting in industrial electrical systems.

Frequently Asked Questions

What is the BUSSMANN FRS-R-20ID fuse used for?

The BUSSMANN FRS-R-20ID is a Class RK5 time-delay indicating fuse rated 20 A, 600 V AC / 300 V DC. It protects motor circuits, transformers, and other inductive loads where temporary inrush currents occur. The built-in indicator visually signals a blown fuse, speeding troubleshooting in industrial control panels and distribution equipment.

What are the specifications of the BUSSMANN FRS-R-20ID fuse?

The BUSSMANN FRS-R-20ID is a Class RK5 time-delay cylindrical fuse rated 20 A, 600 V AC and 300 V DC. It belongs to the FRS-R-ID series and features an integral blown-fuse indicator. The manufacturer part number is FRS-R-20ID. It is designed for overcurrent protection in industrial power circuits.

Where to buy the BUSSMANN FRS-R-20ID fuse worldwide?

3G Electric supplies the BUSSMANN FRS-R-20ID fuse to customers worldwide. As a global industrial distributor, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time. We source and deliver genuine BUSSMANN components for industrial maintenance and OEM applications.

How to select the correct BUSSMANN FRS-R-ID series fuse?

To select the correct BUSSMANN FRS-R-ID series fuse, match the voltage rating (600 V AC or 300 V DC) and current rating (e.g., 20 A for the FRS-R-20ID) to your circuit requirements. The time-delay characteristic handles motor start-up surges. The indicating feature confirms a blown fuse without removal. Always consult the equipment nameplate and applicable NEC/CEC codes.
