More Information
Summary:The invention relates to a trip and closing current circuit of an adaptive circuit breaker. The trip and closing current circuit comprises a forward node and a negative node, wherein two parallel-connected branch circuits are arranged between the forward node and the negative node; a relay is arranged on the first branch circuit, and a current division module is arranged on the second branch circuit. According to the trip and closing current circuit disclosed by the invention, current selection corresponding to a trip and closing circuit and change of the type of the relay are not needed; furthermore, the circuit breaker can be reliably tripped, and a trip and closing coil cannot be burned out.
