Littelfuse L60030 Series 30A 600V Class CC Fuse Block

The Littelfuse L60030 Series Class CC fuse block is a rugged, bolt-in mounting solution for 30A, 600V Class CC fuses used in commercial and industrial power distribution equipment, available across the L60030C-1C, L60030C-1PQ, L60030M-1SQ, and L60030M-2PQ models in 1-Pole and 2-Pole configurations with C, PQ, or SQ terminal styles. Molded from high-strength, high-temperature material and fitted with one-piece copper alloy fuse clips, these fuse blocks use captive pressure-plate terminals for secure, low-resistance conductor termination. A built-in rejection feature keeps lower interrupting- or voltage-rated fuses from being inserted, preserving the 600V, 200,000A interrupting-rating protection that Class CC fuses are designed to deliver. UL Listed, cUL Listed, and CSA Certified for code-compliant installation.

Key Features

  • Ampere Rating: 30A fuse block sized for 30A Class CC fuses.
  • Voltage Rating: Rated 600 VAC / 600 VDC to match Class CC fuse voltage ratings.
  • Rejection Feature: Prevents insertion of fuses with lower interrupting or voltage ratings, so only proper 600V, 200,000A-rated Class CC fuses can be installed.
  • Terminal Options: Available with C, PQ, or SQ pressure-plate terminals that accommodate side- or top-mounted quick-connect terminals for flexible wiring.
  • Pole Configurations: Offered in 1-Pole (L60030C-1C, L60030C-1PQ, L60030M-1SQ) and 2-Pole (L60030M-2PQ) versions.
  • Gangable Design: Interlocking fuse blocks snap together to build a fuse block with any number of poles, reducing part inventory needs.
  • High-Strength Construction: Molded of high-strength, high-temperature material to resist breakage during handling and installation and to withstand heat.
  • Reduced Resistance Fuse Clips: One-piece copper alloy fuse clips offer lower resistance than traditional two-piece brass or phosphor bronze clips, minimizing heat rise and watts loss.

Littelfuse L60030M-1SQ – Frequently Asked Questions

1) Will the Littelfuse L60030 fuse block accept any 30A fuse, or only Class CC?
Only Class CC. The L60030 Series has a built-in rejection feature that blocks fuses with lower interrupting or voltage ratings from being inserted, so the block keeps the 600V, 200,000A interrupting rating that Class CC fuses provide. If your panel drawing calls for a Class J, midget, or Class G fuse, this is the wrong block.
2) I need a 3-pole Class CC block. Can I build one from the Littelfuse L60030?
Yes. The L60030 blocks interlock and snap together, so you can gang single-pole units to make any pole count you need. That is why stocking the 1-pole (L60030C-1C, L60030C-1PQ, L60030M-1SQ) covers most jobs, with a factory 2-pole L60030M-2PQ available when you want it as one piece. Ganging also cuts down how many separate part numbers you carry.
3) What is the difference between the C, PQ and SQ versions of the Littelfuse L60030?
The suffix is the terminal style. All four models use captive pressure-plate terminals for the conductor; the C, PQ and SQ variants differ in how quick-connect terminals land, with PQ and SQ arrangements accommodating side- or top-mounted quick-connects. Pick by how your wiring approaches the block inside the enclosure: L60030C-1C and L60030C-1PQ and L60030M-1SQ are the single-pole choices, L60030M-2PQ the two-pole.
4) Can a Bussmann CHPV2 photovoltaic fuse block be used in place of a Littelfuse L60030 Class CC block?
No, they serve different circuits. The Littelfuse L60030 Series is a 30A, 600V Class CC fuse block with a rejection feature that blocks fuses of lower interrupting or voltage rating, rated 600 VAC / 600 VDC for commercial and industrial power distribution, motor control centers, and panelboard protection. The Bussmann CHPV2 is a modular two-pole photovoltaic fuse block rated 1000 Vdc, built for solar DC strings rather than AC distribution, and it does not take Class CC fuses. If the drawing calls for Class CC protection on a 600V branch or motor circuit, the L60030 is the block to use.
5) I need a two-pole DC fuse block for a solar array - is the Littelfuse L60030M-2PQ the right choice?
For a photovoltaic array, the Bussmann CHPV2 Series is the block built for that duty: a modular two-pole photovoltaic fuse block rated 1000 Vdc. The Littelfuse L60030M-2PQ is a 2-pole Class CC block rated 600 VAC / 600 VDC with pressure-plate terminals, intended for Class CC fuses in power distribution and control panel work. Both are two-pole, but the voltage class and the fuse they accept are different, so match the block to the fuse the system design specifies.
6) Is the Littelfuse L60030 fuse block UL Listed and acceptable in Canada?
Yes on both counts. The L60030 Series is UL Listed under IZLT E14721, cUL Listed under IZLT7 E14721, and CSA Certified under 6225-01 007316. For a spec writer, that covers US and Canadian code-compliant installation in the same part number.
7) Can I use this 600V fuse block on a DC control circuit?
Yes, within rating. The L60030 Series is rated 600 VAC and 600 VDC, matching the Class CC fuse voltage ratings, so it suits DC control circuits at or below 600V as well as AC distribution. For higher DC voltages, such as photovoltaic strings running to 1000 Vdc, you need a different block; the Bussmann CHPV Series is the PV-specific option.
8) Does the Littelfuse L60030 mount to DIN rail or does it bolt in?
It is a bolt-in mounting block, and Littelfuse lists DIN rail mounted control panels among its typical applications along with panelboards, switchboards, and motor control centers. Plan your panel layout around bolt-down mounting.
9) Will the L60030 handle a 20A or 15A Class CC fuse instead of 30A?
The L60030 Series is sized specifically for 30A Class CC fuses. Class CC fuses in the 0 to 30A range share a common body size, but the block itself is rated 30A, so treat 30A as the circuit ceiling and size the fuse to the load within that. Anything above 30A needs a different block and fuse class.
10) Why choose a block with copper alloy clips over standard brass clips?
Heat. The L60030 uses one-piece copper alloy fuse clips instead of two-piece brass or phosphor bronze, which lowers contact resistance and cuts heat rise and watts loss in the enclosure. In a tightly packed motor control center or panelboard where thermal load matters, that is the practical reason to specify it.
11) How is the wire secured in the Littelfuse L60030 fuse block?
Captive pressure-plate terminals. The plate clamps the conductor for a secure, low-resistance termination and stays captive so the screw and plate don't fall out during install, which matters when you are landing conductors in a live-adjacent panel. Housings are molded from high-strength, high-temperature material to resist breakage during handling.
