Overload circuit interrupter capable of electrical tripping and circuit breaker with the same |
摘要 |
The present invention relates to overload circuit interrupter capable of detecting overload and interrupting the overload circuit interrupter, and to a circuit breaker with the same. The overload circuit interrupter (OLCI) in an electrical wiring system includes a current transformer for producing an overload voltage in accordance with the current variation of the phase and neutral conductor, a rectifier for rectifying of the overload voltage, a level controller for limiting the rectified overload voltage, an integrator for charging the limited overload voltage and for providing overload indicative signal, and a comparator for comparing the overload indicative signal with a reference overload voltage and for producing an overload trip signal shutting the AC source off. It can diminish error triggering caused by a dimmer. The circuit breaker may further include an arc fault circuit interrupter (AFCI) and a ground fault circuit interrupter (GFCI).
