Unit-Mount Circuit Breakers
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.
Mounting
H-, J-, and L-frame circuit breakers may be mounted vertically, horizontally or flat on their back without
any derating of characteristics.
Unit-mount H- and J-frame circuit breakers are supplied with two mounting screws, unit-mount L-frame
circuit breakers are supplied with four mounting screws. These mounting screws are inserted through
mounting holes molded into the circuit breaker case and threaded into the mounting enclosure, rails or
through the panel door for flush mounting.
A DIN rail mounting bracket (catalog no. S29305) is available for the H- and J-frame circuit breakers.
NOTE: DIN rail mounting is not compatible with motor operated applications.
