Description
The Eaton Bussmann CVR-J-60400-M (Catalog Number: CVR-J-60400-M, UPC: 051712422857) is a 400 A single-pole modular fuse block cover designed for Class J fuse installations up to 600 V. Specifically engineered to snap securely onto Eaton Bussmann JM series fuse blocks, this non-indicating protective cover provides essential safety shielding for high-amperage power distribution systems.
By fully enclosing live electrical terminals, the CVR-J-60400-M reduces the risk of accidental contact during maintenance while protecting fuse connections from dust, debris, and environmental hazards inside industrial control enclosures.
