Product details
Description/Feature/Scope of Application
The JCM1L series residual current circuit breakers are designed for use in AC 50Hz power distribution networks with a rated voltage of 400V and a rated current of up to 800A. They offer indirect contact protection for individuals and safeguard equipment insulation and ground fault current. Additionally, they support infrequent line switching and motor starting. Unlike conventional models, these circuit breakers feature a three-phase design, ensuring continued operation even if a phase is missing. They allow for on-site adjustment of rated residual operating current and maximum opening time as per specific requirements. Even with a phase voltage drop to 50V, the leakage protection module remains operational and includes a leakage alarm output function. Compliant with IEC60947-2 and GB 14048.2 standards.
