Installation operation diagram
1. Insertion process:
Disconnect the circuit breaker so that the handle is in the withdrawn position as shown in the diagram, then place the circuit breaker into the base guide groove, rotate the interlocking device to the unlocked position, and then rotate the handle in the insertion direction as shown in the diagram to place the handle in the insertion position as shown in the diagram. At this time, the interlocking device should automatically lock and the in place indicator device should be turned on.
2. Extraction process
Disconnect the circuit breaker, turn the interlocking device to the unlocked position, and then rotate the handle in the direction shown in the diagram. At this point, the main contact of the circuit breaker is disconnected from the main contact of the base, and the interlocking device should automatically lock; To prevent the circuit breaker from slipping and being unable to be pulled out, it is necessary to rotate the interlocking device again to the unlocked position, and then rotate the handle in the direction shown in the diagram to place it in the pulled out position. Only then can the circuit breaker be pulled out. (As shown in the above picture)
