Features:
1.This tester is suitable for electronic 2P and 3P circuit breakers. Electromagnetic 1P+N, 2P, 3P, 3P+N, and 4P circuit breakers can all be tested.
2. The simulated residual current provided by this tester is suitable for various types of residual protectors with rated residual operating current below 10A. Test voltage value: Three phase four wire continuous adjustable power supply.
3. The measurement of residual operating current and operating time in this tester is digitized and displayed on a 3-digit semi luminous crystal digital tube. After the residual protector is activated, the display of the measured value can still be maintained for easy reading and recording.
4. Normal working conditions of the tester:
a. Temperature range of 0-40 degrees Celsius;
b. Relative humidity is 20-85%.
