6.7. Mechanism and electrical
operation
To operate the circuit breaker electrically, control
power must be available. The section entitled
Racking describes the application of control power
through the secondary disconnect when the circuit
breaker is in the Test and Connect positions.
1. Inspect the initial state of the circuit breaker to
determine the operations available.
a. Close/Open Indicator.
b. Circuit breaker position Test or Connect (or
control power applied externally if
withdrawn).
2. Energize Control Power.
a. Wait until “READY” lamp is on; approximately
two minute maximum depending on control
voltage with 48 V DC taking the longest
amount of time.
b. Circuit breaker is ready to perform C-O
operation.
3. Close the circuit breaker using the close push-
button or by electrical signal to the magnetic
actuator.
a. The magnetic armature moves down.
• Close/Open indicator changes to Closed.
• READY” lamp illuminates again after about
one second.
b. Circuit breaker is ready to perform O-C-O
operation.
4. Open the circuit breaker using the manual OPEN
push-button or by electrical signal to the
magnetic actuator.
