Detailed Product Description

Application
The item is in accordance with standards of IEC61008, applying to the circuit of AC50/60Hz, 230V single phase, 400V three phases and below it for industrial and mining enterprise, trade building, commerce and family. To mainly prevent electric fire and personal casualty accident caused by personal electric shock or leakage of electrified wire netting. It is a current-operated, fast leakage protector of pure electromagnetic type, which can break off fault circuit rapidly in order to avoid occurrence of accident. The item is precise in structure, less elements, without auxiliary power and high working reliability. The function of the switch won't be influenced by ambient temperature and lighting. The mutual inductor of the item is used to test vector differential value of passing current, and produces a relevant output power and add it to the tripper in secondary winding, if the current of vector differential value of protected circuit of personal electric shock is up to or over leakage operating current, the tripper will act and cut off so that the item will take effect of protection.
Construction features
- Measuring component and buckling component of products is located between enter line end and entrance line end;
- Movement characteristic of products can not be changed with outside mechanical tool;
- The operating organization has the free function to take off and buckle;
- Operate part can not be taken down from the shell outer of products, the shell can not influence the operating organization to work, the accessory group which replace the feelers pressure, should guarantee the feelers pressure does not change while running.
