Structure and working principle

The earth leakage circuit breaker consists of an ADB3 mini circuit breaker and an earth leakage releaseassembled together.When there is leakage or personal electric shock in the protected circuit, the vector sum of the current throughthe zero sequence current transformer is not equal to zero, the secondary coil of the transformer generates avoltage signal and is amplifed by the integrated circuit. When the rectification value is reached, the leakagerelease actuates, so that the circuit breaker cuts off the power within 0.1 seconds, thus playing the role ofelectric shock and leakage protection. When an overload and short circuit occurs in the line or equipment, the overload release or instantaneousrelease in the circuit breaker acts to cut off the power supply and protect the line and equipment from damage.
