⑬：Type of theneutralpole (N) of four-pole product is divided into four types:
Type A:Do notinstall the overcurrent release for pole N andpole Nis
always connected and does not open and close with the other three poles.
Type B:Do not install the overcurrentreleasefor pole N andpole Nopens
and closes withthe other threepoles(Pole N closes first,openslater).
Type C:Install the overcurrentrelease for pole N andpole Nopensand
closeswith the other three poles (Pole N closes first,openslater).
Type D:Install the overcurrent release for poleN and pole N isalways
connected and does not open and close with the other three poles.
⑭：Purpose: No code: power distribution protection 2: motor protection
Twin-type:the outline of the thermo magnetic smart breaker with smart current
protection for the same frame size no matter how the breaking capacity
and rated current is as the following picture.
The rated current,short-circuit short-time delay,short-circuit in stantaneousness and
actuating time for the smart breaker are adjustable.The userself can adjust them as
required. Meanwhile it also has backup protection function, ensuring the line security
when the current changes suddenly.
Install the accessories quickly
