RCBO Electrical Circuit Breakers LFRD-T6301

Definition:

A residual current device (RCD) is the generic term for a device which monitors the current in the line conductor and the neutral conductor of a circuit in an earthed system.

For use in domestic, commercial and industrial installations.

In a normal healthy circuit, the vector sum of the live and neutral current values added together will be zero. Current flowing to earth, due to a line earth fault, will return via the earth conductor, and regardless of load conditions, will be registered as a fault. 


This current flow will give rise to a residual current (Ires) which will be detected by the device. If the Ires exceeds the rated sensitivity of the RCD, it will automatically activate a tripping of the faulty circuit, thereby protecting people, equipment and buildings from the risk of electrocution and fire.


Residual Current Devices ( RCD's ) range Advantage:

•Sensivity

- from 10 to 500mA

•Voltage 

- 2 poles : 230V - 4 poles: 230/400V

•Connection capacity 

- 25A: 6/10 mm² (flexible/ rigid cable) - 40,60A: 16/25 mm² - 80,100A: 35/50 mm²
