Our factory offers OEM services for manufacturing this device with your brand and logo. For more information, please . EAL-18 Residual Current Operated Circuit Breaker (without Overcurrent Protection) is suitable for AC 50 Hz, rated voltage 2P 240V, 4P 400V, and rated current 1-63A. This device quickly disconnects the power supply when electric shock or leakage current exceeds the specified limit, providing protection for personnel and electrical equipment. It can also be used for infrequent switching and starting of the circuit. Type A RCDs (RCCB/ELCB) detect pulsating DC residual current and are suitable for applications involving equipment with electronic components such as inverters, Class I IT equipment, power supplies for Class II equipment, lighting systems with dimmers and LED drivers, and electric vehicle charging equipment producing smooth residual DC current under 6 mA. Type A devices are also compatible with Type AC applications. Complies with IEC/EN 61008-1. Features bilateral busbar connection design for flexible installation in various electrical environments. Maximum conductor size 35 mm², wiring torque 3.5 N·m, suitable for a wide range of electrical installations. (1) Superimposed smooth DC current of 0.006 A on pulsating DC residual current (2) Residual pulsating DC current (3) Equivalent to AC type residual current
