Product Description

The BUSSMANN Medium Voltage Fuse: BCLS Series is a time-delay bolt-on fuse, specifically an R-Rated model (MPN 5BCLS-44R) rated at 5 kV AC and 800 A. This indicating fuse is designed for medium-voltage applications, providing overcurrent protection with a time-delay characteristic.

Frequently Asked Questions

What is the BUSSMANN BCLS Series medium voltage fuse used for?

The BUSSMANN BCLS Series medium voltage fuse, model 5BCLS-44R, is used for overcurrent protection in medium-voltage circuits. Its time-delay characteristic allows it to withstand temporary inrush currents, making it suitable for motor and transformer protection in industrial power distribution systems.

What are the specifications of the BUSSMANN 5BCLS-44R fuse?

The BUSSMANN 5BCLS-44R is an R-Rated, time-delay, indicating fuse rated at 5 kV AC and 800 A. It is part of the BCLS series and features a bolt-on design for secure mounting. The indicating function provides visual confirmation of operation, aiding maintenance in medium-voltage applications.

Where to buy BUSSMANN 5BCLS-44R fuses worldwide?

BUSSMANN 5BCLS-44R fuses are available to order through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact 3G Electric for sourcing and delivery of this BUSSMANN medium voltage fuse.

How to select the correct BUSSMANN BCLS series fuse for an application?

To select the correct BUSSMANN BCLS series fuse, verify the system voltage (5 kV AC maximum) and continuous current rating (800 A for the 5BCLS-44R). Ensure the R-Rating matches the required short-circuit current withstand. The time-delay characteristic is ideal for circuits with high inrush, such as motors or transformers.
