Function:
• The PRCD-S+ switches all poles when tripped: In the event of a fault, the power
supply via L and N is interrupted and the signal unit on the device lights up or blinks
red. For additional safety, the PE conductor contact nevertheless remains closed until
the fault has been cancelled. When the fault has been remedied, the PRCD-S
+ can
be activated again by pressing the button.
• Every time the device is plugged in, a routine check is performed to test the safe
condition of the socket outlet (mains).
• The PE conductor circuit is switched on in advance (leading) and switched off with a
delay
• In case of undervoltage (e.g. ≤ 180 V) or voltage interruption (≥ 20 ms) the internal
undervoltage protection switches the device off and prevents it from restarting
automatically after voltage recovery.
• The integral surge voltage protection detects increased voltages and the PRCD-S+
cannot be switched on or is being switched off (e.g. ≥ 285 V).
• The PRCD-S+
cannot be switched on or switches itself off, if a conductor is
interrupted, and/or a fault voltage is measured on the PE conductor..
• In the event of a fault voltage on the PE conductor, the protection device switches off
the L and N conductor but maintains the connection to the PE conductor circuit.
The PRCD-S+ detects and protects in the case of the following faults:
• L-conductor interrupted
• N-conductor interrupted
• PE conductor interrupted
• External voltage on the PE conductor
• Undervoltage or voltage failure
• Surge voltage (overvoltage)
• DC voltage
• Wiring errors (L and PE conductor reversed)
• Fault currents with rated values of 30mA or 10mA
