HMJBC-701 Single Phase Relay Protection Tester

Microcomputer Relay Protection Tester,
Relay Protection Tester,
Three-phase Relay Protection Calibrator

Product Description


HMJBC-701Single Phase Relay Protection tester is applied to test protection replay based on voltage and current operation. The main function of the tester include calibration of voltage and current operation relays, secondary circuit inspection, trip value of circuit breaker test, switch on and off time measurement of circuit breaker and so on. It’s a low cost, simple operation and reliable performance device for secondary circuit test.


  1. Small size, light weight, fully functional, and convenient to carry.
  2. The performance is superior to similar products both domestically and internationally, with a leading level.
