With this application, the position signaling switches indicate whether the molded case circuit
breaker is inserted in the plug-in socket and secured by at least one bolt. The reason for this
application is that the molded case circuit breaker needs to be secured in position by
fastening bolts in the plug-in socket. The four fastening bolts supplied with the complete kit
for plug-in technology must be used for this purpose.
