SD-ZBS Series Current Protection Relay
Characteristics：
SD-ZBS series of residual current operated relay is a kind of specified smart current leakage device, designed for industrial power equipment. There are 4 tap positions of this product. You can choose rail or embedded, optional four parameters of the product from the technical parameters table according to the terminal facility. It uses microprocessor chip, having wide measuring range, high accuracy, no delay alarm, no delay circuit breaker and delay circuit breaker are set and controlled separately. With zero-sequence current transformer and circuit breakers to form a complete current leakage protection system. It applies to the power system up to AC660V for current leakage protection of the downstream line or power equipment, to prevent the power equipment and personnel from damage or electric shock cause of current leakage.
