Frequently Asked Questions

What is the BUSSMANN JCK-4R medium voltage fuse used for?

The BUSSMANN JCK-4R is an R-rated, time-delay indicating fuse used for overcurrent protection in medium voltage circuits up to 2.54 kV AC. It is commonly applied in motor starters, transformers, and switchgear where coordination with other protective devices is required.

What are the specifications of the BUSSMANN JCK-4R fuse?

The BUSSMANN JCK-4R is a JCK Series, R-rated, time-delay cylindrical fuse rated for 2.54 kV AC and 130 A. It features an indicating function that visually signals when the fuse has operated. The manufacturer part number is JCK-4R.

Where to buy BUSSMANN JCK-4R fuses worldwide?

BUSSMANN JCK-4R fuses are available to order through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations, ensuring you receive genuine BUSSMANN components for your medium voltage protection needs.

How to select the correct BUSSMANN JCK-4R fuse for an application?

To select the correct BUSSMANN JCK-4R fuse, verify your system voltage does not exceed 2.54 kV AC and the continuous load current is below 130 A. Confirm the R-rating coordinates with upstream and downstream devices. Always consult the manufacturer's time-current curves for proper selectivity.
