UNI-T UT582+ Digital RCD ELCB Tester

UNI-T UT582+ Digital RCD ELCB Tester in Sri Lanka

Single-Phase RCD Trip Time and Ramp Test Instrument

The UNI-T UT582+ Digital RCD ELCB Tester is a professional single-phase residual current device tester designed for verifying the trip time and trip current of RCDs, ELCBs, and RCCBs in domestic and light commercial electrical installations. It supports rated currents from 10mA to 500mA and delivers accurate test results at both 0° and 180° phase angles to verify device performance under real-world fault conditions.
