Residual current circuit breakers |
The residual current operated circuit breakers have a measuring system consisting of a summation current transformer with a permanent magent tripping device. RCDs offers protection against dangerous currents through body in the event of touch voltage and in the event of direct contact with a live contactor. |
The protections against dangerous currents through the body are: |
in the event of touch voltage being to high due to bodily contact with the operating device (this is protection in the event of indirect contact with the service circuit)
in the event of direct contact with a live conductor, when IDN<30mA and where dangerous currents through the body need to be disconnected in shortest time (protection in the event of direct contact) |
protection against the occurence of electrically ignited fires |
