High-frequency residual current circuit breaker VDF-100

ACDC

VDF-100 is a kind of circuit breaker with complete update of residual current detection, based on current type A RCCB. It can not only effectively protect AC and pulsing DC（A type）, the possible compound residual current (F type ) , but also smoothing DC and high frequency residual current(1KHz) .In a circuit consisting of rectifier, inverter, frequency inverter, etc, the leakage current caused in DC loop circuit can be effectively detected and protected. Application Industry, medical, EV charger, elevator, etc Conforms to standard IEC/EN61008-1, IEC/EN62423 ; certified by CCC, SEMKO, CE Detection residual current type AC+A+ smoothing DC +F+ high frequency signal (1K Hz)
