USE AND MAINTENANCE
1, the miniature circuit breaker lightning overload characteristics of overload short-circuit by the manufacturer tuning, in the course of not allowed to adjust.
2, Lightning Residual Current Circuit Breakerr, in the new installation and power failure before the trial must be pressed before the button to ensure the normal trip to put into use, in normal use, must try to jump once a week.
3, Lightning Residual Current Circuit Breaker in the scope of protection, the use of power tools and equipment, you must try to press the button to ensure the normal trip before they can be put into use.
4, in the wet weather or thunderstorms, before each use must press the test button to ensure the normal trip to put into use.
5, the mine lightning Residual Current Circuit Breaker failure or press the experimental button can not trip when the user immediately stop using, as soon as possible to return to the factory repair.
6, anti-lightning Residual Current Circuit Breaker by the failure of the electrical system and sub-gate after the need to identify the reasons for troubleshooting before closing.
7, Lightning Residual Current Circuit Breaker to touch the same time by the protection circuit caused by the risk of electric shock, can not be protected.
8, according to national standards "leakage protection function is to provide indirect contact protection." "In the event of other protective measures failure ... can not be the only direct contact protection."
