漏电断路器“每月按一次”是什么意思

无论什么牌子的配电箱，里面的任何一种漏电断路器都有这样的标识。
“每月按一次”的意思就是你应该至少每个月按动一次这个按钮，按下这个按钮时，断路器将跳闸，证明漏电保护功能有效，这是一个测试按钮。
实际使用中也没什么人一个月去按一次，但最好是经常去检查一下能发现漏电保护器出故障了。如按下试验按钮，漏电保护器应跳闸，否则就是坏了。不过在按按钮的时候时间不要太长，跳闸了就要马上松手，不然漏保里的实验电阻会烧的.

No matter what brand of distribution box, inside any kind of leakage circuit breakers have such identification.
"Monthly press" means that you should have at least once a month by pressing the button, press this button, the circuit breaker will trip proved effective leakage protection, this is a test button.
Actual use but also no one to press once a month, but it is often best to check leakage protection can be found out of order. If you press the test button, leakage protection should trip, otherwise it is bad. But do not press the button when the time is too long, the trip would immediately let go, or leakage protection in experimental resistance will burn.
