① Pull the lock lever toward you (step 1), unhook the lock lever from the cradle, and then pull out the extension rail (step 2).

Step 1

② With the extension rail pulled out to the furthest position, lift the breaker once by using a lifter or dedicated lifting hook (HP), and then lower the breaker down onto the drawout rail. Place the dent of the breaker onto the notch of the drawout rail. (Fig. 12-5)

③ With the extension rail pulled out to the furthest position, slowly push the breaker in until you hear the clicking sound when it does not move.

When inserting the breaker from the DRAWOUT position to the

DISCONNECT position, be sure to do so evenly on the right and left sides. (Do not forcefully push the right or left terminal area only.)

If it is uneven (if the breaker is inserted diagonally), it does not go in smoothly.

For a breaker installed in an elevated location, perform this operation with two people.

⑦ When the breaker is inserted to the testing position, the drawout position indicator shows TEST position, and the lock plate is protruded automatically, locking the drawout handle rotation.

(Caution)

Do not rotate the drawout handle while the lock plate is protruded.

⑧ Insert the lock plate, and rotate the drawout handle clockwise. When the breaker is inserted to the CONNECT position, the lock plate is protruded automatically, completing the insert operation. At this time, the drawout position indicator shows the CONNECT position. For all breaker types, the operation load becomes heavy during operation from the TEST position to the CONNECT position or at the main circuit junction insertion position, but this is not a fault.

CAUTION

Be sure to insert until the lock plate is protruded. If it is not protruded, the connection may be incomplete.

(Caution)

(a) After completing the insertion, do not rotate the drawout handle.

(b) The drawout position indicator shows the position

(CONNECT, TEST) when the lock plate is protruded.

When the lock plate is unlocked, it shows a reference position.

(c) The breaker cannot be closed with the drawout handle inserted.
