三菱电机公司根据市场需要开发出新型高性能漏电报警断路器。它的主要作用是连续监视电路有无漏电。当发生漏电时,不切断电路,而是发出报警信号,以确保供电的连续性。这种漏电报警断路器应用了可抑制高次谐波和电压脉动的 IC 元件,因此,不仅操作方便、监视精度高,而且实现了小型化。其特点是如下。 Mitsubishi Electric developed a new type of high-performance leakage alarm circuit breaker according to market needs. Its main function is to continuously monitor the circuit for leakage. When a leakage occurs, do not cut off the circuit, but issued a warning signal to ensure the continuity of power supply. This type of earth-leakage alarm circuit breaker uses IC components that suppress harmonics and voltage ripple. Therefore, it is easy to operate, has high monitoring accuracy, and is miniaturized. Its characteristics are as follows.
