China Portable Automatic Residual Current Circuit Breaker Tester RCCB Tripping Current Tester IEC-62561-1 IEC-62305-1residual Current Device Tester Ch

1. General Information
EPHV-NT Model B residual current circuit breaker tester (hereinafter referred to as the tester) is specially developed for the performance test of residual current circuit breaker. It is the key instrument to detect the trip current and break time of type B residual current circuit breaker.
The functions of the tester can meet the test requirements for residual current circuit breakers in IEC61008-1:2012 MOD, IEC 61009-1: 2012, MOD standards.
The tester is suitable for electronic and electromagnetic residual current circuit breakers. Circuit breakers of 1P+N, 2P, 3P, 3P+N and 4P can be tested, and the maximum residual current output is 2A.
The function of the tester is operated by touch screen. After the circuit breaker is operated, the tripping current and breaking time can be maintained, which is convenient for reading and recording.
The system display and operation adopt the popular industrial touch screen, which is simple to operate.
Please read the instructions carefully before using the instrument.
