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.
