Detail PCE‘s PRCD-S

PCE‘s PRCD-S+ protects the user reliably against incorrect electrical installations.

• Before every switch-on procedure and during operation a fully automatic verification is performed in order to check the correct supply conditions. → The classic “test button” is eliminated.

• Measuring errors are indicated by the signal unit flashing red. In this case, the  from  PCE gives a visual warning and does not switch on.

 • The LED signal unit (red/green) visualizes error situations and offers a permanent status indication.

 • The PE conductor circuit is switched on in advance and switched off with a delay.

• Failure situations like external voltage on the PE conductor or fault current above rated values cause an interruption of L and N. The PE conductor stays closed and keeps being monitored!

• The integral surge voltage protection detects 400 VAC and 220 VDC and does not allow these to pass (a weak point occurs).

• Undervoltage will be recognized and the  switches off.

• The  recognises conductor interruptions or wiring errors from the source system.
