The EKL21-63S Residual Current Circuit Breaker (RCCB) is Economical of our company's development in circuit protection technology. This RCCB is ideal for residential and commercial circuits, supporting a rated voltage of 240V for two poles and 415V for four poles, with a rated current of up to 63A. It offers unmatched safety by swiftly disconnecting power when personal electric shock risk or power grid leakage current surpasses safety thresholds. The EKL21-63S RCCB ensures rapid response to protect both human life and electrical appliances.
