Mersen 60302j Fuse Block Class J 2 Pole 600V 30A

Product Description

The MERSEN 60302j is a Class J fuse block rated for 30 amps and 600 volts, designed for 2-pole non-spring reinforced installations using a box connector configuration. Fuse clips are constructed from high-conductivity tin-plated copper, providing reliable contact without the added tension of spring-reinforced clips. Insulators are molded from glass-filled polycarbonate or phenolic materials, with verified dielectric strength exceeding 2500 volts. This fuse block is well-suited for licensed electricians and industrial maintenance technicians working on branch circuit protection and power distribution panels.

The 60302j fits into applications requiring a compact, reliable Class J fuse holder for branch circuit or feeder protection. The box connector style accommodates a wide range of stranded or solid copper or aluminum conductors. This block also features a unique adder block configuration, allowing it to be snapped onto 1-, 2-, or 3-pole blocks to build multi-pole segmented assemblies with as many poles as the application requires, making it a flexible option for panel builders and service electricians working on custom distribution assemblies.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize and lock out the circuit before installing or replacing fuse blocks. Verify that conductor size and insulation rating are appropriate for the 30A, 600V application before terminating wires at the box connector. Do not exceed the rated amperage or voltage of this fuse block.
