CR.100A
Introduction to the CR.100A:
-
Contact resistance tester outputs DC 100A current to test the contact resistance of circuit breaker or high current cable contacts.
It is designed according to IEC62271.
-
The main application being the measurement of circuit breaker contact resistance.
-
All the test results can be printed by the micro-printer which is integrated in the tester.
-
Also, all the saved test results can be uploaded to PC and converted to MS WORD document.
