TKEL3 Series Residual Current Protection Circuit Breaker

The TKEL3 series residual current protection circuit breaker is designed for AC 50Hz circuits, supporting a rated insulation voltage of 800V, a rated operating voltage of up to AC 400V, and a rated operating current of up to 800A. It is also suitable for low-voltage power grids with a directly grounded neutral point in three-phase four-wire systems. This breaker provides indirect contact protection against electric shock hazards while safeguarding circuits and electrical equipment by monitoring grounding, current, voltage, and frequency. Additionally, it features high-precision measurement, comprehensive sensing, multiple communication options, and automatic reclosing for leakage protection.
