The JCL-A-2R fuse from Bussmann/Eaton is a 70 A, high‑voltage motor‑circuit protection cartridge designed for medium‑voltage systems. It uses a single‑barrel JCL construction with an AmpGard hookeye connection and is rated for up to 4.8 kV AC, enabling fast interruption of motor faults in industrial equipment. Common applications include motor feeders and starter circuits where a 70 A, 4.8 kV, single‑construction fuse is required, and it integrates with standard Bussmann/JCL mounting arrangements used in MV fuse blocks.
