Product Description

 KEDU 4P 25A Residual current circuit breakers with VDE CB CCC CE approved


Applicable scope:

CKDL 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.

Features

The residual current action uses pure electromagnetic type,its detection,discrimination and breaking action function is independent of the power supply voltage,overcoming the defects of poor anti-interference of electronic products,great fluctuation to the power grid voltage and protection failure due to broken neutral line,presenting reliable action.
