Title: Circuit breaker
Inventor: HAYAKAWA HIDEKI
IPC: H01H73/00
Filed: 1997-11-20
Abstract: PROBLEM TO BE SOLVED: To provide a small-sized circuit breaker equipped with a tripping device having a wide operating voltage range. SOLUTION: In a steady state, the positive input of an operational amplifier 10 is fed with a voltage obtained by dividing a supply voltage Va through resistors 13, 14, and the negative input is fed with a constant voltage obtained through a Zener diode 12. A signal is output to the operational amplifier 10 to control a transistor 9, so that the positive and negative input pins are brought at the same potential. As a result, the supply voltage Va is determined by the constants of the resistors 13, 14 and the Zener diode 12. In an operating state, a thyristor 16 is turned on by a trip signal from an overcurrent detecting circuit and the supply voltage Va is applied to a tripping device 17.  The supply voltage Va is determined by the constant of a Zener diode 7 connected between the base and collector of a transistor 6 for constant voltage because the voltage at the positive input pin of the operational amplifier is reduced, thus the output of the operational amplifier 10 is zeroed and the transistor 9 for control is turned off.
