The Mobile latest generation personal protection device.
With peace of mind!
Anyone who wants to use an electrical outlet of an existing electrical installation for commercial purposes must take appropriate protective measures in advance. PRCD‑S pro meets this requirement.
Fault-free switching on with gloves
With the PRCD‑S pro, it makes no difference whether users wear gloves or not, thanks to the latest electronics.
Fault-free switching on is possible at all times under all operating conditions.
Determining the quality of the protective earth resistance
The PRCD‑S pro not only detects whether the protective earth PE is connected, but also determines its quality. Switching on is only possible if the resistance of the protective earth RPE is less than 1kΩ ist.
Thus, the PRCD‑S meets the highest safety requirements.
Self-monitoring device
Self-monitoring device
The PRCD‑S pro monitors itself. The classic test button is omitted.
- Functional test of the residual current circuit upon every connection to the socket and every 2 hours of operation – without interruptions
- Relay contact test upon each switch-on and switch-off process
- Monitoring of the resistance of the protective earth RPE
- Indication of the device status and fault signalling using integrated LEDs
Detection of smooth DC fault currents
Electrical loads and equipment can generate smooth DC fault currents.
If these are connected to an electrical circuit with a Type A fault current circuit breaker, these smooth DC fault currents cause the fault current circuit breaker to not function.
The PRCD‑S pro detects smooth DC fault currents > 6 mA safe!*

DGUV 203–006 konform
DGUV Information 203–006 (DGUV – German Social Accident Insurance) requires the use of appropriate protective measures when connecting electrical equipment to unfamiliar sockets, e.g. use of a portable residual current device according to DIN VDE 0661:
- Rated differential current I∆n ≤ 30 mA
- All-pole switching, including protective earth
- No independent restart after restoration of voltage
As well as the following functions:
- Must not be able to be switched on if the protective earth is interrupted or is under voltage
- Must be switched off if voltage is present at the protective earth during operation or if the protective earth is interrupted
- The protective earth must not be switched off if external voltage is present on the protective earth
Behaviour of the PRCD‑S pro in the event of a fault
Break wire N (or L)
Cannot be turned on.
Break during ongoing operation: Interruption of L and N. PE remains closed.
Protective earth breakage
Cannot be switched on. No power at PE > 1 kΩ.
Interruption of L and N during ongoing operation when PE > 1 kΩ.
Break PEN conductor
Cannot be switched on.
Break during ongoing operation: Interruption of L, N and PE.
Wiring fault, PE and L reversed
Cannot be switched on.
Undervoltage
Cannot be switched on.
Interruption of L, N and PE during ongoing operation.
Fault current according to technical data
Interruption of L, N and PE.
Voltage on PE when switching on
Cannot be switched on.
Fault-free operation even when wearing gloves.
External voltage on PE, e.g. drilling a line
Interruptions of L and N
PE remains closed
