Product Identity

The EATON BUSSMANN CVRI-J-60100-M is an open fuse block cover rated for J UL Class fuses between 70 and 100 amps. It fits 600 V AC systems and carries CSA certification and UL listing for code-compliant installations. Dimensions are 8.8 in length, 2.0 in width and 2.9 in height.

Intended Use

Electrical contractors and maintenance teams specifying J-class fuse blocks in the 61 to 100 A range will find this cover matches the JM60100-1CR, JM60100-2CR and JM60100-3CR bases. Buyers needing protection for other fuse classes or amperages outside 70 to 100 A should select a different cover.

Sustained Load Behaviour

Under continuous operation at rated current the cover remains mechanically secure and maintains its indicating function without deformation. The UL-listed construction resists heat buildup during prolonged 600 V AC service, keeping clearances stable over the duty cycle.

Questions about this item

Which fuse blocks does this cover fit?

It fits the JM60100-1CR, JM60100-2CR and JM60100-3CR fuse blocks.

Can I use it on a 60 A J-class block?

The cover is rated for 61 to 100 A, so a 60 A block falls outside the specified range.

How do I confirm the cover is indicating correctly after installation?

The indicating feature shows fuse status visually; verify the indicator matches the fuse condition once the cover is secured.
