SD-ZLD Series Current Protection Relay
Characteristics:
SD-ZLD type(ZLD-G type is rail-style installation)current leakage protection relay is a kind of smart device specifically designed for industrial power equipment. It takes microcomputer-controlled chip, having the features such as wide range of measurement, high precision and so on.
Used together with L type residual current transformer and circuit breaker forms current leakage protection system. It applies to power system up to AC690V for current leakage protection of the downstream line or power equipment, to prevent the power equipment and personnel from damage or electric shock indirectly cause of current leakage.
