purpose

BLD-20 High voltage leakage protection device ( Hereinafter referred to as relay ) Mainly used for AC voltage 1-10KV In the system , The frequency is 50HZ, Leakage to power supply system ( Or ground ) Achieve selective protection .

The relay can be connected with the circuit breaker with shunt release or voltage loss release , AC contactor , Magnetic starter and other components of leakage protection device , For leakage and electric shock protection , It can also be equipped with buzzer , Various sound and light indicating devices such as signal lamps are combined into a leakage alarm device .

The relay is small , Imported power supply , Long term stable power supply , The installation method is divided into two structures. One is suitable for the standard in the installation cabinet 35mm Guide rail installation , The other is panel mounting , Opening 45X45mm, The current value of leakage action is directly fixed and adjustable by grades , Reliable movement , Easy to operate , It can adapt to various occasions and can be used to ground the line for fault protection , Prevent equipment accident or electrical fire caused by grounding fault current , It is suitable for non neutral grounding leakage protection of voltage system and underground 1-10KV No neutral grounding , Leakage protection in high voltage distribution system . It is a new product of network reform for safe use . The action time of the relay is divided into fast type and time-delay type .
