Electric Motor Operator
45
General
The motor operated mechanism is designed to open, close
and reset a circuit breaker or switch by remote control. The
customer must supply the circuit breaker or switch normally
ON and OFF push buttons, external wiring, a control power
source, and all control logic. Consult the wiring diagram
(Figure 3, page 47) for a typical control connection.
The motor operator is hinged for opening to the left or right
dependent on catalog number designation. The “L” suffix
means the motor operator is hinged to the left. A motor
operator hinged to the right uses no suffix.
NOTE: For automatic reset operation a separate auxiliary
contact must be provided by the customer. See page for
more details.
