LYR9N RCBO

Description：

Scope of application
LYR9N residual current operated circuit breaker is suitable for Ac 50Hz,rated voltage 240V,rated current up to 40A.When people come to electric shock or the leakage current ofthe network exceeds the specified value, it can quickly cut off the faultypower supply in very short time to protect the safety of people and electrical equipment. At the sametime,it can protect the overload or short circuit ofthe line, and can also be used for infrequent switching of the line.it’s suitable for terminal distribution lines in commercial office building sresidential and general industrial use.
