PRCD-S (3-phase) 

➭

Switch mains power on by 
turning the right-hand rotary 
selector switch to the 

3~ ON

 position.

6.3.1

Simulated Interruption

 

➭

Start with the left-hand rotary se-
lector switch in the first 

ON

 position in the 

green area for single-phase interruption.

➭

Switch through the positions, one after 
the other, in the clockwise direction (ta-
ble from top to bottom).

Conductor Interruption Using a 3-Phase PRCD from Kopp as an Example 

Regarding step 8:

The N LED also lights up due to star connection, although N is interrupted!

Note!

Tripping performance may deviate 
from this example in the case of 
PRCDs from other manufacturers – 
adhere to the manufacturer’s test 
instructions!
