Main Features
[Type AC Residual Current Protection] Detects sinusoidal AC residual currents and disconnects the circuit when earth leakage is detected.
[Automatic Reclosing] Automatically attempts to restore power after a trip when operating conditions return to normal.
[Reduce Unnecessary Site Visits] Designed for circuits where automatic power restoration can reduce manual reset and maintenance requirements.
[Built In Protection and Test Function] Combines residual current detection, automatic trip operation and a TEST function for routine checking.
[DIN Rail Electrical Installation] Suitable for distribution boards, remote equipment and unattended electrical circuits requiring automatic recovery.
