Details: KLD0-SAA


Pepperl+Fuchs Segment Protectors feature a safety switch off for explosion protection at typically 31.5 V.

In rare cases the tolerances in other manufacturers’ power modules in combination with very short cable lengths with little or no voltage drop lead to a switch off of the Segment Protector.

The KLD0-SAA is used to limit the voltage to uncritical values.

The KLD0-SAA is installed in close proximity to the power supply within the control cabinet.
