Our factory can provide OEM service to manufacture this device with your brand and logo. If you have any needs, please feel free to contact the seller! EAL-18 Residual Current Operated Circuit Breaker (without Overcurrent Protection) is suitable for AC 50 Hz, rated voltage 2P 240V, 4P 400V, rated current 1-63A line. When a person receives an electric shock or the network leakage current exceeds the specified value, the residual current device will actuate the circuit breaker to quickly cut off the faulty power supply within a short time, protecting personnel and electrical equipment. It can also be used for the infrequent switching and starting of the circuit. Type A RCDs (RCCB/ELCB) detect pulsating DC residual current. Type A devices are also suitable for Type AC applications. Suitable for installation in circuits where equipment contains electronic components such as inverters, Class I IT equipment, power supplies for Class II equipment, lighting equipment including dimmers and LED drivers, and electric vehicle charging equipment with smooth residual DC current less than 6 mA. Complies with IEC/EN 61008-1. Features bilateral busbar wiring capability for wider application in various installations. Maximum connection capacity of 35 mm, wiring torque 3.5 Nm, suitable for a variety of installation equipment. (1) Residual pulsating DC current superimposed with a smooth DC current of 0.006 A (2) Residual pulsating DC current (3) Equivalent to AC type
