Two-Pole Class J Fuse Block
The Bussmann JM60060-2CR is a two-pole fuse block rated for 600 VAC and 300 VDC. It accepts UL Class J fuses in the 35 to 60 A range and is built for industrial line protection. The open design suits panel builders and maintenance crews who need accessible, bolt-down or DIN-rail mounting.
35–60 A Capacity With Box Lug Terminals
The block handles continuous loads up to 60 A through box lug connectors that accept 14 to 2 AWG conductors. At 600 VAC the assembly provides reliable isolation for motor circuits and control panels. Headroom ends at the 60 A fuse limit and the 300 VDC ceiling, so higher-current or higher-voltage DC feeds require a different block.
Thermoplastic Body With A4 Stainless Hardware
A thermoplastic housing carries the live parts while A4 stainless steel hardware resists corrosion in damp or chemical environments. Bolt-down slots and DIN-rail compatibility give installers two mounting choices without extra brackets. The 3.70 in. length, 3.00 in. width and 2.60 in. height fit standard enclosures, and the block carries UL Listed, CSA Certified, CE, RoHS and REACH marks.

Questions about this item
Will this 600 VAC fuse block fit on the same DIN rail as my existing 35 A J-class fuses?
Yes, the JM60060-2CR mounts on DIN rail or bolt-down and accepts 35 to 60 A Class J fuses such as the LPJ, JKS and DFJ series.
How can I verify the block is making proper contact after wiring it with 2 AWG conductors?
Check that the box-lug terminals are torqued to spec, confirm the fuse seats fully in the open design, and measure continuity across both poles at 600 VAC or 300 VDC rating.
Does the package include the Class J fuses or only the thermoplastic two-pole block?
Only the fuse block is supplied; 35–60 A Class J fuses (LPJ, JKS, DFJ) and mounting hardware must be purchased separately.
