CFR7-100B integrates an electronic residual current detection module and an electromagnetic residual current detection module. The detection of high frequency residual current and smooth DC residual current within 1kHz is realized by an electronic circuit, combining the advantages of electromagnetic and electronic type.

Leakage protection and isolation, high short circuit withstand capability. Also provides the indirect protection against the operator and protection of the fire caused by the electric circuit faulty.
