-
COMPLETE CIRCUIT PROTECTION: Combines a WiFi automatic reclosing accessory with a 1P+N 6kA RCBO to provide residual current, overload and short circuit protection in one coordinated set.
-
TYPE A : Type A for AC and pulsating DC residual currents generated by modern electronic appliances.
-
REMOTE ON OFF CONTROL: Connect the set to a 2.4GHz WiFi network and use the Smart Life app to remotely open or close the circuit without an additional gateway.
-
AUTOMATIC POWER RESTORATION: The motor operator performs up to three reclosing attempts at 30 second intervals after the RCBO trips, reducing unnecessary site visits caused by temporary faults.
-
COMPACT 1P+N SOLUTION: Suitable for homes, shops, farms, pumps, outdoor equipment and remote distribution panels requiring leakage, overload and short circuit protection together with smart operation.
