Abstract

See full text

An over-energy protection circuit, a residual current device, an electronic device, and a power distribution box. The protection circuit has relatively high operating reliability, and includes: a first over-energy absorption circuit, a second over-energy absorption circuit, and a residual current determining circuit. The first over-energy absorption circuit receives a first electrical signal output from a current transformer; and when a voltage value of the first electrical signal is greater than or equal to a first preset threshold, performs step-down processing on the first electrical signal to obtain a second electrical signal, and outputs the second electrical signal to the second over-energy absorption circuit; or when a voltage value of the first electrical signal is less than a first preset threshold, outputs the first electrical signal to the second over-energy absorption circuit.
