What is the insulation resistance of a basic switch?

ID: FAQE20019E



The insulation resistance of a basic switch indicates the resistance (1) between the same polarity terminals, (2) between the charged metal part and ground, and (3) between each terminal and the uncharged metal part.


The insulation resistance is measured with an insulation resistance meter (Megger) between the following: two points of the same polarity terminals between COM-NO in the FP state and between COM-NC in the TTP state (in the case of the c-contact specification).
