Bussmann CVRI-J-60100-M Fuse Block

CVRI-J-60100-M is a 100 A, 600 V AC Class J fuse block cover with indication for use with JM modular fuse blocks. This indicating cover attaches to Class J fuse blocks to provide a visible status indication of the fuse condition, enabling rapid fault identification in panels and power-distribution assemblies. It is designed for 1-pole configurations and pairs with the JM60100-1CR fuse block, a 100 A, 600 V Class J block with knife-blade ends. The indicating variant is intended to show fuse status (indicating) whereas the non-indicating counterpart is CVR-J-60100-M for setups that do not require status visibility. Typical applications include industrial control panels, motor control centers, and other electrical distribution equipment where Class J fuses are used, and the cover is compatible with standard JM-series Class J blocks within Eaton Bussmann's product line.
