The YCW1i series intelligent universal circuit breakers are designed for AC 50Hz distribution networks with a rated voltage up to 400V/690V. Covering a comprehensive current range, they serve to distribute electrical energy and provide reliable protection against overload, undervoltage, short circuit, and single-phase grounding faults. The series features intelligent protection functions with precise selectivity, enhancing power supply reliability and preventing unnecessary outages. Equipped with an open communication interface, these breakers support remote monitoring and control (“four remotes”), making them suitable for integration into modern automation systems and control centers. Compliant with IEC 60947-2 standards, they can also be used for infrequent line switching under normal operating conditions.
