LD-13 Earth Leakage Circuit Breaker Tester Calibration Device

An earth leakage circuit breaker tester is also known as an RCD tester, earth leakage switch detector, earth leakage protector tester, residual current device (RCD) detector, or residual current device (RCD) tester. The earth leakage protector tester is primarily used to measure the earth leakage operating current, non-operating current, and operating time of earth leakage protectors. Years of operational experience both domestically and internationally have shown that the testing performance of earth leakage circuit breaker testers directly impacts the selection of earth leakage switches by users and their electrical safety. Therefore, calibrating earth leakage circuit breaker testers is crucial.

Flux Technology (Nantong) Co., Ltd.'s LD-13 Earth Leakage Circuit Breaker Tester Calibration Device is specifically designed to provide comprehensive calibration for earth leakage circuit breaker testers. Using this standard device, the main measurement functions of earth leakage circuit breaker testers can be fully calibrated, allowing for a comprehensive and accurate assessment of their metrological performance. The LD-13 fully meets the metrological requirements of "JJF1283-2011 Calibration Specification for Operating Characteristic Testers of Residual Current Operated Protective Devices."
