SKU CH-TQ5C-F4N6M

Finger-safe fuse block for Class J and CF fuses up to 30 A, 600 V AC or 300 V DC, DIN-rail mount with box-lug terminals for 18 to 8 AWG wire

  • Finger-safe design protects against accidental contact
  • Accepts 18 to 8 AWG wire for versatile connections
  • DIN rail mounting enables quick panel installation
  • UL Listed and CSA Certified for code compliance
  • Rated 600V AC and 300V DC for industrial circuits

Class J Fuse Block 0-30 A

The Bussmann TCFH30N is a single-pole Class J fuse block rated 600 V AC and 300 V DC for fuses up to 30 A. It accepts Class CF and FCF/TCF series fuses measuring 1-7/8 in long by 3/4 in wide by 1 in deep. The finger-safe box-lug terminals take 18 to 8 AWG conductors and the fiberglass-reinforced thermoplastic body mounts on standard DIN rail.

Panel Builders Needing Compact Single-Pole

This block suits panel builders who need a UL Listed, CSA Certified Class J fuse holder with a small 2.3 in by 0.75 in footprint. It is not for applications requiring multi-pole ganged units, indicator windows, or fuse sizes outside the 0-30 A range. Installers needing screw-mount bases or larger wire ranges should look at other series.

18 to 8 AWG Box-Lug Terminal Range

The wire-range specification decides fit: only solid or stranded conductors between 18 and 8 AWG can be terminated in the box lugs. Verify your conductor size before ordering, as larger or smaller gauges will not secure properly in this block.

Questions about this item

How much heat does the 600V AC rated block generate when carrying a 30 A load all day?

The fibre-reinforced thermoplastic body and box-lug connectors are rated for 30 A continuous duty at 600 V AC, so normal operation stays within UL temperature-rise limits for industrial fuse blocks.

What wire gauges and fuse series must I already have to install this single-pole unit?

You need 18 to 8 AWG copper wire and a Class J fuse from the FCF or TCF series, 1-7/8 in long, 0 to 30 A.

Will the finger-safe box lugs accept the same 18 to 8 AWG wire used on my older Class J clips?

Yes, the box-lug connector accommodates 18 to 8 AWG conductors, matching the wire range of many legacy Class J fuse blocks.
