Residual current characteristic type
The residual current operating protector is a current protection device. Will trip when a ground current occurs. They always calculate the vector sum of single-phase or three-phase system currents. If the vector sum is zero, normal power supply is provided. If the vector sum reaches or exceeds a preset value (depending on the sensitivity of the device), it can automatically open the circuit. As an integral protection element, it can provide grounding. Fault current protection and overload and short circuit protection. The series of electronic residual current action protection circuit breakers are products specially designed for household distribution lines. The breaking capacity is economical, affordable, safe and reliable to install.
