Our factory can provide OEM service to manufacture this device with your brand, logo, if you get any need, feel free to contact the buyer! EAL-18Residual current operated circuit breaker(NO Overcurrent Protection)is suitable for AC 50HZ, rated voltage2P 240V, 4P 400V,rated current1-63Aline. When a person gets an electric shock or the grid leakage current exceeds the specified value, the residual current will actuate the circuit breaker to quickly cut off the faulty power supply in a short period of time to protect the safety of personnel and electrical equipment. It can also be used as the infrequent switching and starting function of the line Type A RCDs RCCB ELCB detect pulsating DC Residual Current. Type A devices are also suitable for Type AC applications.Installed to protect circuits where equipment with electronic components such as-inverters,-Cla 1 IT equipment,-power supplies for Cla II equipment,-lighting equipment including dimmers and LED drivers,-electric vehicle charging equipment with smooth residual DC current le than 6 mA. ~In compliance with IEC/EN61008-1.~ Bilateral busbar wiring capabilities to adapt to the wider use of premises.~Maximum connecting ability of 35mm , wiring torque 3.5N*m, applicable to a variety of installing equipment. (1) The remaining pulsating DC current is superimposed with A smooth DC current of 0.006a (2) Residual pulsating DC current.(3) Of the same type as AC.
