Safety Interlocks
SecoGear is designed with a number of interlocking
systems to help prevent improper operation:
• The circuit breaker can be moved from “Test” to
“Connect or service” position and vice versa only when
the circuit breaker is in the “Open” position
• The secondary disconnect plug can be inserted or
removed only when the circuit breaker is in the “Test”
position
• The circuit breaker cannot be closed when it is in-
between the “Connected or Service” and
“Test/Disconnect” positions
• When the circuit breaker is moved from the “Connect or
Service” position, the metal shutters will close
automatically
Secondary Disconnect Interlocking
The secondary disconnect plug is latched in place when
the breaker is racked into the connected position.
Figure 6-9 shows the disconnect plug unlocked, and
Figure 6-10 shows the locked position.
