Professional OEM/ODM manufacturer of power distribution electrical equipment.

Residual Current Circuit Breaker (RCCB) K7

Porduct Overview The K7 solving the problem of RCCB high current specifications is an important supplement to leakage protection products with working current less than or equal to 63A. This move not only improves the performance of leakage protection equipment, but also expands its application range, enabling it to better meet the safety needs of various electrical equipment and systems. By adding support for large current specifications, the K7 RCCB product can more effectively cope with high-load current environments, ensuring that reliable leakage protection can still be provided when the current exceeds the conventional specifications. This not only improves the safety of electrical systems, but also provides users with more choices and flexibility, allowing leakage protection equipment to play its due role in various industrial and civil occasions. Choose the K7 for uncompromising, efficient residual current protection that meets and exceeds the requirements of modern, high-power electrical systems. Trust ETEK Electric to deliver the reliability, performance, and safety your industrial-grade electrical installations demand.
