Characteristics of locking fault alarm contacts:

1 normally open, 50VDC (200mA)

Auto coincidence:

In automatic mode, detect the load end and automatically reclose after a 5-second delay if it meets the closing requirements; The closing was unsuccessful. The load side was tested and met the closing requirements. The second reclosing was delayed for 15 seconds. However, it was unsuccessful. The load side was tested and met the closing requirements. The third reclosing was delayed for 30 seconds and was unsuccessful. The device entered the locking state and the locking alarm contact was connected, sending an alarm signal. After 15 minutes, the lock state will be automatically released and the action will be repeated according to the overlapping process.

(If the load end detection does not meet the closing requirements or trips again within 5 seconds after closing, it is defined as unsuccessful closing)

Release lock:

After eliminating the leakage fault, manually close the circuit or press the remote closing button (when there is remote control function) to close and release the lock; Or wait for 15 minutes before automatically unlocking.

Manual/Automatic Operation:

Set [Manual/Automatic] to automatic mode, manually open the circuit breaker, default to fault tripping, and it will automatically reclose; Press the remote disconnect button to trip and enter the locked state.

Set [Manual/Automatic] to manual mode, automatic reclosing and remote control functions will be disabled, and manual opening or closing can be performed.

Security padlock:

When in the open state, it can be locked with a locking diameter of Φ 4mm.

Communication:

Standard RS485 communication interface, in compliance with DL/T "Residual Current Operated Circuit Breaker Communication Protocol" requirements; It can achieve remote control and intelligent management such as opening, closing, and querying operation status from a distance.
