Porduct Overview

EKL21-63S residual current circuit breaker (RCCB) is a cost-effective circuit protection solution specifically designed for the Central Asia and South American markets. It is suitable for both residential and commercial circuits, supporting 1P+N 240V rated voltage and 3P+N 415V rated voltage, with a rated current of up to 63A. In the event of a risk of electric shock or if the ground fault current exceeds the safety threshold, this RCCB can swiftly disconnect the power supply to ensure unparalleled safety. It can be used in conjunction with the DZ47-63S miniature circuit breaker produced by ETEK Electric to achieve comprehensive circuit protection.
