Attention
(i) Never fail to remove the extension handle when the opening/closing operation is over or
when UVT trip button and/or ELCB test button are
operated or tripped. Otherwise it may give the in-
ternal mechanism a severe shock or reduce its
service life or may get into the air when the circuit-
breaker trips.
(ii) Refrain from using such organic solvent as thinner
for cleaning the panel (decorative sheet) or handle.
(iii) Handle position with the door open:
While the door is open, the handle position at OFF may shift. This results naturally from
the structural feature of the external handle. It is not anomaly.
(iv) When the door is to be opened with the circuit-breaker ON, open it with the release pin left
turned in the arrowed direction.
(v) It is difficult to manipulate the trip button of the circuit-breaker in case of 2 poles. Some
metallic wire rod in L-shape shall be prepared.
2 2 S type handle 2
2 2
This handle, intended to manipulate the inboard circuit-breaker
from without, shall be used when it is to be provided on the
door side.
(a) Opening/Closing operation
• Rotating the handle clockwise will turn the circuit-breaker
ON.
• Rotating the handle counterclockwise will turn the circuit-
breaker OFF.
• When the circuit-breaker trips, it can be reset if the handle
is rotated counterclockwise further than OFF position.
(b) When locking
The external handle can be locked at ON and OFF positions. Raise the locking metal of the
external handle and shut a padlock. If the locking metal cannot be raised, move the external
handle so that the metal should fit into the groove of the decorative sheet. The padlock shall
be supplied by user. Up to 3 padlocks may be attached under normal conditions.
Dimensions of padlock
The padlock to be used shall be commercially available one.

Note. S type external handles for WSS (S05SW to S4SW)
display the trip when the circuit-breaker trips even if the
locking is ON. [Only when one padlock (35mm, 50g or
less) is provided.]
Attention
(i) Such organic solvent as thinner shall not be used for cleaning the panel (decorative sheet)
and external handle.
(ii) Opening/closing the frontal sheet
a) When the front sheet is to be opened, open it gently with the external handle left oper-
ated in the OPEN reset direction. When it is to be closed, close it after matching the
position of the circuit-breaker handle with that of the external handle.
Never try to close the frontal sheet as left slided forcibly. Otherwise, the parts of the
external handle may impinge against the handle of the circuit-breaker to damage it.
b) If the frontal sheet is to be opened with the circuit-breaker ON, open it with the release
pin left turned in the arrowed direction.
