A type RCDS

 
  • RCD performance data

specific applications :
dedicated lines

A type RCDs, in addition to the characteristics of AC type units, also detect residual currents with DC components. Used each time the fault currents are not sinusoidal.
They are particularly suitable for dedicated line applications: 
- in residential premises, on specialised cooker or hob circuits, or specialised washing machine circuits. 
- in other installations, on circuits where class 1 equipment may produce fault currents with DC components, such as variable speed drives with frequency inverter, etc.
