Product Details
1. Product Name:
Contact resistance tester HYHL-600A
2. Equipment Description:
400A and 600A are same panel design.
Contact resistance tester output DC 600A/400A/300A/200A/100A
current to test the contact resistance of circuit breaker or high
current cable contacts. It is designed according to IEC62271. The
main application of the tester is measurement of circuit
breaker contact resistance. All the test results of the tester
could be print by the micro-printer which is integrated in the
tester. Also all the test results saved in the tester could be
upload to PC computer and then convert to MS WORD document.
