The “Earthed Fault Current” is the flow of electricity from the power supply leaking towards the earth, under faulty electrical condition. Its degree of danger depends on the amount of leakage and the surrounding conditions.
Users of leaking equipment may get electrical shock. If this current persists for a long time, fire hazard may be caused. A residual current operated circuit breaker can be installed on the distribution system in order to detect the leakage and cut off the circuit before any damaged occurs.
GREEGOO’s offer both residual current operated breaker with (the RCBO) and without (the RCCB) integral over-current protection. Both breakers employ zero current transformer (ZCT) and permanent electro-magnet or electronic tripping mechanism, giving a high sensitivity for detecting and cutting off faulty current.
GDS9 - Electromagnetic RCBO
The electromagnetic RCBO series GDS9 offers a complete protection for single-phase circuit. The series has innovative two-colour operation lever (red and green), which enables users to check the status of the device in a distance. Also the tripping status can be observed on the front indicator window of the device.
The rated leakage current to activate these devices can be chosen from 30mA. The breaking current capacities according to IEC 61009 are 4.5kA (GDS941 type), 6kA (GDS951 type).
