Product Description

The MERSEN A480R Series is a time-delay cylindrical fuse, specifically an R-rated medium voltage fuse with a 4.8 kV AC rating and 200 A capacity. This indicating fuse, model A480R9R-1, is designed for overcurrent protection in industrial electrical systems.

Frequently Asked Questions

What is the MERSEN A480R9R-1 medium voltage fuse used for?

The MERSEN A480R9R-1 is an R-rated, time-delay medium voltage fuse used for overcurrent protection in industrial electrical systems. It protects motor circuits, transformers, and switchgear operating at 4.8 kV AC. Its indicating feature allows quick identification of a blown fuse, reducing downtime in plant maintenance.

What are the specifications of the MERSEN A480R Series fuse?

The MERSEN A480R Series fuse is an R-rated, time-delay cylindrical fuse rated at 4.8 kV AC and 200 A. The specific model A480R9R-1 is an indicating fuse. It is designed for medium voltage overcurrent protection in industrial environments. The manufacturer part number is A480R9R-1.

Where to buy MERSEN A480R9R-1 fuses worldwide?

You can source the MERSEN A480R9R-1 fuse from 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time. 3G Electric supplies genuine MERSEN components for industrial applications.

How to select the correct MERSEN medium voltage fuse for a motor circuit?

To select the correct MERSEN medium voltage fuse, match the voltage rating (e.g., 4.8 kV AC) and current rating (e.g., 200 A) to your circuit requirements. For motor protection, use an R-rated time-delay fuse like the A480R Series to handle inrush current. Always consult the manufacturer's application guide for coordination.
