Hi

We usually conduct the following tests:
a) IR test in both open and close condition
b) Contact resistance measurement
c) Timing test

An additional test could be DCRM (Dynamic contact resistance measurement).

Don't forget to test the insulation system.

 

[unclebob]

A phase contact resistance
B phase contact resistance
c phase contact resistance?

How about close, open and trip?
