The MERSEN 60605J is an Add-A-Fuse fuse block rated for 60 amps and 600 volts. It provides a modular fusing point that can be added to an existing electrical distribution system without replacing the primary fuse block assembly. The unit accepts standard fuse sizes consistent with its 60A rating and is suited for industrial and commercial electrical panels, motor control centers, and similar power distribution equipment. Licensed electricians and electrical contractors install this component as part of branch-circuit overcurrent protection work.
The 60605J is used in applications requiring supplemental or add-on fuse protection at 600 volts or below. Typical installations include industrial machinery, HVAC equipment disconnects, control panels, and commercial power distribution boards where additional overcurrent protection points are needed without a full panel redesign. It is appropriate for both new installations and retrofit scenarios in facilities requiring expanded circuit protection capacity.
Designed as an OEM-style add-on fuse block for use in industrial and commercial electrical distribution systems rated up to 600 volts and 60 amps.
Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the circuit before beginning any work on the fuse block or connected wiring. Verify that the ampere and voltage ratings of the block match the circuit requirements before installation. Do not exceed the 60A or 600V ratings under any operating condition.
