Bussmann CHCC3DU Class CC Fuse Block, 3-Pole, 0-30A

The Bussmann CHCC3DU is a Class CC fuse block engineered to hold and protect fuses rated from 0 to 30A. Configured with 3 poles, this fuse block delivers multi-circuit overcurrent protection in a single, space-saving assembly ideal for panelboards, control panels, and industrial equipment specifying Class CC fuses. Model CHCC3DU combines a proven fuse-holding design with the compact footprint that electrical contractors, panel builders, and OEMs rely on for organized, code-conscious circuit protection across commercial and industrial installations.

Key Features

  • Amperage Rating: Accepts Class CC fuses rated from 0 to 30A, giving specifiers flexibility across a range of branch and control circuit loads.
  • Class CC Fuse Compatibility: Purpose-built for Class CC fuses, a fast-acting, current-limiting fuse class widely specified for branch circuit and control circuit protection.
  • 3-Pole Configuration: Three independent pole positions let a single block protect three circuit conductors from one mounting location, reducing panel clutter.
  • Model CHCC3DU: Identified by manufacturer model number CHCC3DU for straightforward cross-reference, spec-matching, and replacement ordering.
  • Space-Saving Block Design: Consolidates multiple fuse positions into one compact assembly, simplifying panel and control cabinet layout and wiring.
  • Bussmann Manufacturing: Produced by Bussmann, a long-established supplier of circuit protection components used throughout commercial and industrial electrical systems.

Bussmann CHCC3DU – Frequently Asked Questions

1) Can I protect a three-phase circuit with one CHCC3DU block?
Yes. Three independent pole positions mean one CHCC3DU covers three circuit conductors from a single mounting location, which is why panel builders use it for three-phase branch and control circuits instead of three separate holders.
2) I need 600V Class R or Class G protection instead of Class CC. What should I use?
The CHCC3DU will not take those fuses. For Class R at 30A, the Littelfuse LFR60030-3CID is a 600V 3-pole Class R block. For a 600V Class G circuit at 15A on DIN rail, the Littelfuse LFG60015-1SQDINR covers it. For larger bolt-in power blocks, the Littelfuse LD Series POWR-BLOKS line is the one to look at.
3) What is the closest 3-pole alternative to the Bussmann CHCC3DU if the panel calls for Class R fuses instead of Class CC?
The Bussmann CHCC3DU is built specifically for Class CC fuses rated 0 to 30A in a 3-pole block. If the drawing specifies Class R, the Littelfuse LFR60030-3CID is a Class R fuse block rated 600V 30A. Fuse classes are not interchangeable in a block: a Class CC fuse is physically rejected by a Class R clip and vice versa, so match the block to the fuse class the panel schedule lists.
4) For a 30A three-circuit feed, how do the Bussmann CHCC3DU and Littelfuse LFR60030-3CID compare?
Both cover three poles at 30A. The Bussmann CHCC3DU accepts Class CC fuses rated 0 to 30A, a fast-acting current-limiting class widely used for branch and control circuits. The Littelfuse LFR60030-3CID is a Class R block rated 600V 30A. The deciding factor is the fuse class your specification and existing fuse stock call for, since the clips accept only their own class.
5) Is the CHCC3DU suitable for a control panel build, or only a panelboard?
Both. It is specified for panelboards, control panels, industrial machinery wiring, and OEM panel assemblies, and the compact block format is what keeps a control cabinet layout tidy when three fuse positions have to live in one spot.
6) Can I use the CHCC3DU to replace an existing Class CC fuse holder in a machine panel?
That is one of its intended uses. Bussmann lists the CHCC3DU for retrofit and replacement of Class CC fuse holders, so if the circuit already runs 0-30A Class CC fuses and you need three poles, the block is a direct functional swap. Confirm your mounting footprint and wire range against the old holder before you cut anything over.
7) Do fuses come with the Bussmann CHCC3DU?
No. The CHCC3DU is the fuse block only, the carrier that holds and protects the fuses. You order the Class CC fuses separately, sized to the circuit anywhere in the 0 to 30A range the block accepts.
8) Is a Class G fuse block a substitute for the Bussmann CHCC3DU?
No. The CHCC3DU holds Class CC fuses rated 0 to 30A across three poles. The Littelfuse LFG60015-1SQDINR is a Class G block rated 600V 15A for DIN rail mounting. Class G and Class CC fuses differ in body dimensions and rejection features, and the Class G unit covers a 15A ceiling, so it is a different circuit protection device rather than a drop-in for a Class CC block.
9) What should I use instead of the Bussmann CHCC3DU if I need a bolt-in block rather than a Class CC holder?
The CHCC3DU is a compact Class CC fuse block for panelboards and control cabinets. Where the application calls for a bolt-in mounted block, the Littelfuse LD Series POWR-BLOKS fuse block uses bolt-in mounting. Confirm the fuse class your circuit requires first, since the CHCC3DU is purpose-built for Class CC fuses and that choice drives which block fits.
10) I need a DIN rail mounted fuse block for a control panel - does the Bussmann CHCC3DU mount that way?
The CHCC3DU is described as a compact Class CC block for panelboards, control panels, and industrial equipment, with three independent pole positions from one mounting location. If DIN rail mounting is the requirement on a single-circuit control feed, the Littelfuse LFG60015-1SQDINR is a DIN rail mount block, though it is a Class G unit rated 600V 15A and holds a different fuse class.
11) How do I make sure I am ordering the right Bussmann part number for a spec'd Class CC block?
Order against model CHCC3DU, the Bussmann manufacturer model number, which is what you cross-reference on a drawing or an existing panel label. It is the 3-pole, 0-30A Class CC version, so a 1-pole or 2-pole position count on the spec means a different part in the family.
