EKL9-40 products provide protection against earth faults, overloads, short circuits and over-voltage in commercial and domestic installation. The RCBO with both disconnected neutral and phase guarantees its proper actuation against earth leakage faults even when the neutral and phase are wrongly connected the electronic RCBO incorporate a filtering device preventing the risks of unwanted due to transient voltages and transient currents.

  1. This is RCBO can be wired from the bottom and top.

  2. Provides protection against earth fault/leakage current and function of isolation.

  3. High short-circuits current withstand capacity.

  4. Applicable to terminal and pin/fork type busbar connection.

  5. Equipped with finger protected connection terminals.

  6. Fire resistant plastic parts endure abnormal heating and strong impact.

  7. Automatically disconnect the circuit when earth fault/leakage current occurs and exceeds the rated sensitivity.

  8. Independent of power supply and line voltage, and free from external interference, voltage fluctuation.

  9. Rated current can reach up to 40A.
