Mechanical Lugs
Unit-mount H-frame and J-frame circuit breakers can be ordered with mechanical line and load side
lugs. The standard lugs can be removed for the installation of compression-type lugs or bus
connections. All lugs are UL Listed for their proper application and marked for use with aluminum and
copper (Al/Cu) or copper only (Cu) conductors. Lugs suitable for copper and aluminum conductors are
made of tin-plated aluminum. Lugs suitable for use with copper conductors only are made of copper.
Mechanical Lugs for the H- and J-frame circuit breakers lay on top of the circuit breaker terminals and
can be installed without the use of any tools. The lugs are held in place with snap features built into the
insulative retainer and are secured with the clamp force applied to the wire binding screw.
Mechanical lugs come in both aluminum and copper versions and are sold either factory installed or as
field installable kits.
