SKU CH-5BXD-BBQR3

Time-delay Class J fuse rated 25 A at 600 V AC with a 200 kA interrupt rating for industrial circuit protection

  • Product typeFuses & Accessories
  • UL 248-8 Class J listing confirms code compliance
  • 200 kA interrupt rating at 600 V AC handles large fault currents
  • Time-delay dual-element design rides through motor inrush
  • 25 A 600 V AC rating suits standard industrial circuits
  • 2-1/4 in x 13/16 in cylindrical body fits LFJ fuse blocks

Littelfuse JTD025 Class J Time-Delay Fuse

This UL Listed Class J fuse provides time-delay overcurrent protection for industrial power circuits. It is engineered for 25 A at 600 V AC and 300 V DC with a 200 kA interrupt rating at 600 V AC. The cylindrical melamine body fits standard non-rejection fuse blocks.

Interrupt Rating 200 kA at 600 V AC

The 200 kA interrupt rating at 600 V AC is the critical specification that determines if this fuse can safely clear a fault on your supply. A lower rating risks catastrophic failure during a short circuit. Verify your system's available fault current before specifying this device.

Dual-Element Design for Motor Loads

The dual-element construction tolerates temporary inrush currents typical of motor starting without nuisance opening. It coordinates with compatible LFJ series fuse blocks for secure mounting. This fuse does not suit applications requiring visual indication or rejection-style block mounting.

Questions about this item

What does the 25 A rating mean when this fuse is installed in a circuit?

The fuse will carry up to 25 amperes continuously and open on sustained overloads while tolerating brief inrush currents thanks to its time-delay design.

How does the Class J 600 V AC rating limit where this fuse can be used?

It is UL Listed for circuits up to 600 volts AC with a 200 kA interrupting rating, and also rated for 300 volts DC at 20 kA.

What physical dimensions must the fuse block or holder accommodate?

The cylindrical body measures 2-1/4 inches long by 13/16 inch in diameter and fits non-rejection style Class J fuse blocks such as the LFJ series.
