Cooper Bussmann JCL-A-9R Fuse

The Cooper Bussmann JCL-A-9R is a current-limiting, high-voltage fuse designed for motor circuit protection in industrial power systems. Rated at 200 A and 5.08 kV AC, the JCL-A-9R is part of Bussmann’s R-rated family and is built for fast interruption of heavy fault currents to safeguard motors and drives. It features a bolt-on body and, in common configurations, Westinghouse Ampguard hookeye terminations for straightforward integration into existing switchgear or motor control centers; some listings also reference Edison-style assemblies. The fuse carries an 80 kA interrupting rating and is intended for medium-voltage motor protection applications, with typical overall dimensions around 15.76 inches in length and 3.0 inches in diameter, enabling compatibility with standard fuse housings. This part is suitable for installation in MCCs, motor starters, and other mid-voltage motor circuits where reliable protection against short circuits is essential.
