Bussmann CVR-RH-60030 Fuse Block Terminal Cover
The Bussmann CVR-RH-60030 Fuse Block Terminal Cover is a purpose-built protective cover designed to shield the terminals of compatible fuse blocks from accidental contact during normal operation and routine maintenance. Compact in size at .95 in. long, 7.2 in. high, and 1.93 in. wide, and weighing just .5 lb, this cover installs directly over the fuse block terminal area to add a layer of physical protection in commercial and industrial electrical enclosures. As part of the Bussmann circuit protection accessory line, the CVR-RH-60030 is engineered to complement Bussmann fuse block assemblies, helping electricians and maintenance staff keep exposed terminal areas covered between service intervals. Its low-profile shape allows it to fit into panel and enclosure layouts without adding significant bulk around the fuse block assembly.
Key Features
- Compact Dimensions: Measures .95 in. (L) x 7.2 in. (H) x 1.93 in. (W) for a low-profile fit directly over the fuse block terminal area.
- Lightweight Design: At just .5 lb, the cover is easy to handle, position, and install during panel assembly or field maintenance work.
- Terminal Protection: Shields exposed fuse block terminals to help reduce the risk of accidental contact while personnel work in or near the enclosure.
- Bussmann Compatibility: Designed as a dedicated accessory for the CVR-RH-60030 fuse block application, supporting correct fit and function.

Bussmann CVR-RH-25030 – Frequently Asked Questions
1) How do I know which Bussmann CVR-RH cover matches my fuse block?
Match the cover to the voltage and amperage rating of the fuse block it goes over. The CVR-RH covers come in four versions: CVR-RH-25030 for 250V/30A, CVR-RH-25060 for 250V/60A, CVR-RH-60030 for 600V/30A, and CVR-RH-60060 for 600V/60A blocks. A 30A cover will not span a 60A block body, and the 250V and 600V blocks differ in size, so ordering by the block's rating is the whole decision here.
2) Is the Bussmann CVR-RH cover the same thing as a Class R fuse block, or does it go on one?
The Bussmann CVR-RH is a protective terminal cover only, not a fuse block. It installs over the terminal area of a compatible fuse block to shield exposed terminals during operation and maintenance, and comes in 250V/30A, 250V/60A, 600V/30A and 600V/60A ratings to match the block it covers. If you need the block itself, a Class R block such as the Littelfuse LFR60030-3CID, rated 600V 30A, is the current-carrying device; the CVR-RH does not carry current or hold fuses.
3) I need a 600V 30A fused disconnect point for a DIN rail panel - will the CVR-RH work?
The CVR-RH is a terminal cover, so it does not provide a fusing point on its own. For a DIN rail layout, the Littelfuse LFG60015-1SQDINR is a Class G fuse block rated 600V 15A with DIN rail mounting. If you need 600V 30A in Class R, the Littelfuse LFR60030-3CID covers that rating. The Bussmann CVR-RH, offered in 250V/30A, 250V/60A, 600V/30A and 600V/60A versions, is the accessory you add over the terminals once the block is selected.
4) What does a Bussmann CVR-RH cover actually do, and is it required?
It is a snap-over terminal shield for a Bussmann fuse block, not a live electrical component. Its job is to keep the exposed terminal area covered so hands and tools do not make accidental contact while someone is working in the enclosure. Many open-style fuse blocks ship without one, so the cover is ordered separately when the panel needs the terminals guarded.
5) Will the cover have to come off every time I change a fuse?
It is meant to be removed and reinstalled for inspection, testing, or fuse replacement without disturbing the components around it. Plan on lifting it for a fuse swap and putting it straight back on, rather than unbolting anything.
6) I need a fuse block with the terminals already enclosed instead of adding a cover. What should I look at?
Consider a fuse block built as a finger-safe or enclosed unit rather than an open block plus a separate shield. In the Littelfuse line, the LFG60015-1SQDINR is a 600V 15A Class G block on DIN rail mounting, and the LFR60030-3CID is a 600V 30A Class R block. Going that route changes the fuse class and mounting, so confirm your fuse type and panel mounting before switching.
7) We use Littelfuse POWR-BLOKS in our panels. Does the Bussmann CVR-RH cover fit them?
The Bussmann CVR-RH is built as a dedicated Bussmann accessory and is sized to fit Bussmann fuse block assemblies, matched by rating in 250V/30A, 250V/60A, 600V/30A and 600V/60A. The Littelfuse LD Series POWR-BLOKS is a bolt-in mounting fuse block from a different series, so plan the cover from the same family as the block rather than mixing. Where a panel standardizes on Bussmann circuit protection, the CVR-RH drops over the terminal area without reworking the existing layout.
8) We're standardizing a facility on Bussmann circuit protection. Does this cover work with existing panel layouts?
Yes, that is the point of its shape. The low profile is intended to drop over the fuse block terminal area within existing panel and enclosure layouts without reworking surrounding hardware. Order the cover rating that matches each block, since a mixed panel of 250V and 600V or 30A and 60A blocks needs more than one part number.
