Cylindrical 15A 600V AC fuse with melamine body

Bussmann

Bussmann DFJ-15 J Class Fast-Acting Fuse 15A 600V AC

SKU CH-5VDB-D024M

Fast-acting Class J fuse rated 15 A at 600 V AC with 200 kA interrupt capacity

  • Fast-acting protection clears faults quickly
  • 15 A rating suits low-current circuits
  • 600 V AC rating handles industrial voltage
  • 200 kA interrupt rating stops heavy fault current
  • Cylindrical body fits standard Class J fuse blocks

Fuse class and ratings

The Bussmann DFJ-15 is a Class J fast-acting fuse rated at 15 amperes and 600 volts AC. It provides non-indicating protection with a cylindrical melamine body and a 200 kA interrupt rating at 600 V AC. The fuse also carries a 450 V DC rating with a 100 kA interrupt rating. It suits circuits requiring fast response to overcurrent conditions.

Voltage and fuse-block compatibility

Verify that the circuit operates at or below 600 V AC or 450 V DC before installation. The fuse fits non-rejection style fuse blocks and is compatible with CH30J, JM600, JP600, JT600 and JTN600 series blocks. Confirm the existing holder accepts a cylindrical body measuring 2-1/4 inches long by 13/16 inch diameter. Ensure the available fault current does not exceed the stated interrupt ratings.

Replacement and upgrade guidance

This fuse replaces Bussmann DFJ, Littelfuse LDFJ and Mersen HSJ series equivalents in the same ratings. The upgrade is worthwhile when a fast-acting, current-limiting device with a high interrupt capacity is required for branch-circuit protection. It is not suited for applications needing time-delay characteristics or visual indication of fuse status.

Questions about this item

What does the 15 A 600 V AC rating mean for my circuit?

It means the fuse will carry up to 15 amps continuously and interrupt up to 200 kA at 600 V AC, protecting conductors and equipment on a 600 V AC supply.

Which equivalent series should I pick if the DFJ-15 is out of stock?

The Littelfuse LDFJ and Mersen HSJ series are listed as direct equivalents with the same Class J, 15 A, 600 V AC ratings.

What comes in the box and what must I buy separately?

The box contains the single cylindrical fuse only; a compatible Class J fuse block such as the CH30J, JM600, JP600, JT600 or JTN600 series must be purchased separately.
