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.
