ABSTRACT:
A mounting for a circuit interrupter is provided that facilitates the easy removal and insertion of the circuit interrupter. The mounting includes upper and lower terminal and support arrangements that cooperate with upper and lower device mounting studs of a circuit interrupter. The device mounting studs also function as electrical circuit connection points to connect the circuit interrupter in an electrical circuit via respective upper and lower contact assemblies of the mounting. The upper and lower contact assemblies include resilient retention facilities for providing suitable electrical contact forces when engaged with the device mounting studs. The upper and lower terminal and support arrangements retain the circuit interrupter within the mounting and are selectively operable to release the circuit interrupter for removal from the mounting. Each of the terminal and support arrangements include a latch arm that is moved to release the respective device mounting stud from a retained holding position to a latch release position. The mounting also includes a resilient guiding member that cooperates with one or more of the latch arms to retain the circuit interrupter in a latched released position after operation of the latch arm. The resilient guiding member includes a protruding arm that acts against the device mounting stud as the latch arm is moved outwardly to release the device mounting studs.
