Leakage Current Circuit Breaker Tester KEW5410

KYORITSU: Ideal for judging the quality of leakage circuit breakers!

**Features** - **Easy Operation (Remote Measurement)** With the remote measurement function, you can automatically measure just by connecting the measurement code to the terminals. The circuit voltage is displayed first, and after one second, the measurement of operating time or sensitivity current begins. - **Automatic Voltage Detection** There is no need to switch voltages as it automatically detects 100V, 200V, and 400V circuits. - **Operating Time Measurement** It is possible to conduct a rated non-operating current test in the ×1/2 range and measure operating time in the ×1 and ×5 ranges. - **Sensitivity Current Measurement** The test current is automatically increased, and the current value at the point of tripping is displayed. - **Automatic Contact Voltage Detection** When measuring using grounding, to prevent electric shock due to poor grounding, it automatically detects the voltage of the grounding electrode or protective conductor during the leakage current breaker test (when test current is flowing) and stops the measurement at AC50V, issuing a warning. - **Dust and Drip Protection** Complies with dust and drip protection IEC 60529 (IP54). Measurements can be taken even in bad weather. - **Backlight** The backlight allows for reading measurements in dark places.
