SKU CH-3A74-Y12EZ

A single-pole fuse block rated 30 A at 600 V AC with a box lug accepting 14 to 2 AWG wire and a thermoplastic body measuring 7.00 by 1.20 by 2.30 inches

  • Product typeCircuit Breakers
  • Rated for 600 VAC circuits up to 30 A
  • Accepts wire sizes from 14 to 2 AWG in box lug terminals
  • Single-pole open design mounts by bolt-down or DIN rail
  • Thermoplastic body meets UL, CSA, CE, RoHS and REACH
  • Compact footprint of 1.20 in wide by 7.00 in long

Single-pole fuse block for 30 A 600 V circuits

This one-pole fuse block accepts UL Class H fuses up to 30 A at 600 VAC. The thermoplastic body mounts by bolt-down or DIN rail and uses box-lug terminals that take 14 to 2 AWG wire. It is UL Listed, CSA Certified and carries CE, RoHS and REACH markings.

Suited for industrial panels needing a single 30

Installers wiring a 30 A 600 VAC branch will find the open-design block straightforward to mount and terminate. It does not serve DC circuits, multi-pole loads or applications requiring finger-safe covers or a DC voltage rating.

Box-lug terminals accept 14 to 2 AWG conductors

The connector type is the decisive spec: only solid or stranded copper in the 14 to 2 AWG range fits the box lugs. Verify your wire gauge before ordering because larger or smaller conductors will not terminate correctly.

Questions about this item

How do I mount the Bussmann HM60030-1CR fuse block and what is the common wiring mistake?

Bolt it down or clip it onto DIN rail, then insert stripped wire into the box lug and tighten the set screw. The frequent error is skipping the torque step, leaving a loose connection that overheats.

What part of the Bussmann HM60030-1CR will need replacement after a fault?

The fuse block itself stays in service; only the Class H fuse cartridge rated up to 30 A must be replaced after it opens.

At what current does the Bussmann HM60030-1CR reach its thermal limit during continuous operation?

The block is rated for 30 A maximum; sustained loads above that value will exceed the connector's thermal capacity.
