1.Operating handle:
push upward to close,push downward to open.
2.Switch button:
Click-open and close.If the switch is in locked state,you can press and hold 5 seconds to unlock.
3.Manual and automatic switching dialing：
By dialing up and down,the circuit breaker switches between local manual mode and remote automatic mode.
Local manual mode:You can open and close the circuit breaker locally through the operating handle or switch button; you cannot control
the closing of the circuit breaker remotely,but you can control the opening of the circuit breaker and open it to the locked state.In the
locked state,you cannot manually close the circuit breaker,at the same time,it enters the maintenance state.After the maintenance,
if you need to manually close the circuit breaker,press and hold the switch button for 5 seconds to unlock it.Then you can manually close
or remotely close the circuit breaker.
Remote automatic mode:You can open and close the circuit breaker directly through the operating handle or switch button locally:You
can remotely control the closing and opening of the circuit breaker,and open it to the locked state.In the locked state,you cannot manually
close the circuit breaker.When closing the circuit breaker,press and hold the switch button for 5 seconds to unlock it,and then you can
manually open and close the circuit breaker.
4.Indicator status：
Run status indicator light(Run):If green light is always on then it means the circuit breaker is closed,if flashing,it means open.
Network communication light(Communicate):If bluelight is flashing then it means network pairing is in progress,if always on,it means
network communication is successful.Alarm/Lock Indicator(Lock):If redlight is flashingthen it is a product fault alarm,if always on when it’
s opening,it is a fault trip or it can be remotely controlled to lockout.
5. Leakage test button
It is used for self-test of leakage protection.The circuit breaker trips instantly after pressing the button.The handle automatically closes 5
seconds after the test is completed.
