Residual Current Circuit Breakers — LGL Series RCCB
Back
Detailed description

Applicable scope:

LGL series residual current circuit breakers are applied to the lines with AC 50/60Hz,rated voltage of 230V(1P+N) or 400V(3P+N),and rated current of 100A.In case of electric shock or electric leakage current exceeds the specified value,the residual current circuit breaker can switch off the fault circuit in a very short time,protecting the safety of person and electric equipment.
Can be used in the industrial,commercial,high-rise buildings,civil residences and other places.
