Cradle Position Switch
Three series of optional auxiliary switches are available for the cradle:
• Cradle position switches (CE) to indicate the connected position.
• Cradle position switches (CD) to indicate the disconnected position. This
position is indicated when the required clearance for isolation of the power
and auxiliary circuits is reached.
• Cradle position switches (CT) to indicate the test position. In this position, the
power circuits are disconnected and the auxiliary circuits are connected.

Additional Actuators for Cradle
Position Switches on Masterpact NW
Circuit Breakers
A set of additional actuators may be
installed on the cradle to change or add
the functions of the cradle position
switches. Each standard actuator can be
replaced by any other actuator to
change the function of the cradle
position switch.
