Mersen 61006sj Class J Fuse Block 100A 600V

Product Description

The MERSEN 61006sj is an open-style Class J power fuse block rated for 100 amps and 600 VAC/VDC single-phase service. Built from glass-reinforced polycarbonate, the block provides a durable, insulated housing suited for industrial and commercial electrical panels. It accepts 6 to 2/0 AWG wire through a box lug and side clip connection, giving electricians flexibility across a range of conductor sizes. The single-pole design mounts on DIN rail or threaded fasteners, fitting cleanly into most distribution enclosures. RoHS compliant and listed to UL 4248-8 and CSA C22.2, this block meets North American code requirements for fused power distribution circuits.

The 61006sj is intended for use in commercial and industrial power distribution panels where Class J fuse protection is specified. It is part of the 6SJ series and is designed for installations requiring reliable overcurrent protection at voltages up to 600 VAC or VDC. Electricians working on motor control centers, panel boards, and machine control enclosures will find this block appropriate for single-pole branch circuit fusing. The open-style construction allows for straightforward fuse inspection and replacement without disassembling surrounding components.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the circuit before installing or servicing the fuse block. Ensure conductor size and torque are applied per the lug manufacturer specifications printed on the block or in the product data sheet. Do not exceed the 100A or 600V ratings under any load condition.
