What is the difference between electromagnetic and electronic type of residual current circuit breakers?
Electromegnetic type residual current circuit breakers do not need auxiliary voltage for tripping case of any residual current.
Thus it ensures exact safety thereby performing its function independent of supply voltages even in case of low and high voltages. Equipment operating under electro mechanic method maintain to protect residual current in the phase line which they supply even in case of disconnection of neutral line. As the
electronic type residual current circuit breakers need auxiliary voltage, it is risky to use them. Because auxiliary voltage will be disconnected in case of any neutral disconnection they are unable to carry out protection function. Due to such obstacles,electronic type residual current circuit breakers are not allowed to be used in our country by the ministry of public works and settlement.
