Mersen 60607j Fuse Block 600VAC/VDC 60A 2 Pole Class J

Product Description

The MERSEN 60607j is a spring reinforced fuse block rated for 600 VAC/VDC and 60 amps, designed for Class J fuse applications in industrial and commercial electrical systems. Built from glass filled polycarbonate, this two-pole block uses a box lug connection type and accepts wire sizes from 14 to 2 AWG. The threaded mounting configuration allows for secure panel or enclosure installation. Measuring 3.9 inches in length, 3.15 inches in width, and 2.2 inches in height, the block delivers a compact footprint without sacrificing current capacity. Licensed electricians and industrial maintenance technicians are the primary installers of this component.

This fuse block is suited for residential, commercial, and light industrial electrical distribution applications where Class J fusing is specified. It is compatible with AJT, A4J, and HSJ series fuses, making it a practical choice for branch circuit protection panels, machine control enclosures, and equipment disconnect assemblies that require a robust, spring reinforced fuse holder with reliable box lug termination.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lock out the circuit before handling the fuse block or making any wiring connections. Use appropriately rated lugs and torque connections to the specified 45 inch-pounds as noted in the product data. Verify that fuse ratings do not exceed the block amperage and voltage ratings before energizing the circuit.
