2P 40A RCCB EA9 Residual Current Circuit Breaker
1. Introduction of Residual Current circuit breaker
Ea 9 Series Residual Current Circuit Breaker (without over- current protection) is suitable for the line of AC50/60Hz, voltage 240V(2 pole)/ 415V(4 pole), rated current up to 63A. When there is human electricity shock or if the leakage current of the line exceeds the prescribed value it will cut off the power rapidly to protect human safety and prevent the accident from the current leakage. It is applicable to industrial area, commercial area, tall building and civil house.It complies with standard IEC/EN 61008.1 and GB1696.1
