Connection
Rear Connection
For connection of bus bars or cables with compression lugs. Rear connections are easily installed on
the circuit breaker terminals. The same connection may be installed flat, edgewise or at a 45° angle.
All combinations are possible. The circuit breaker is mounted on a backplate.
Mechanical Lugs
Unit-mount H-, J-, and L-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/CSA Certified 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
insulating retainer and are secured with the clamp force applied to the wire binding screw.
Mechanical lugs are sold either factory installed or as field installable kits.
