ABSTRACT:
A trip control device for monitoring and tripping a circuit breaker includes a first voltage detector 11 and a second voltage detector 12 for detecting the first and second reference voltages corresponding to the maximum allowable voltage level and the operation resumable voltage level, wherein the second reference voltage is set higher than the first reference voltage. The output of the second voltage detector 12 at logical 1 reduces the output of the first voltage detector 11 to the logical 0 through a transistor 14 and a capacitor 15 with a predetermined delay. The logical sum T of the outputs of the first voltage detector 11and the second voltage detector 12, output from the OR gate 13, turns off the drive circuit 3 when at logical 0, to de-energize the electromagnetic coil 4 and render the associated circuit breaker incapable of being made.
