Wholesell 4p B Type RCCB Htl1-63 Detect High Frequency AC and Smotth DC Earth Residual Currents

       B type RCCB HTL1-63 Application

B type RCCB use for protect  inverters for PV installations ,speed control in HVAC ,some running machines ,UPS , medical equipmen and charge pole for electic vehiches etc,this B type RCCB in addition to standard 50Hz earth leakage currents ,smooth DC and high frequency AC residual current can't detected by AC or A type RCCB , B type RCCB makes up for this defect.

B type RCCB was design accorcding to standard IEC/EN61008  and IEC/EN62423.In addition to normal AC ,B type RCCB also can detect high frequency AC and smotth DC earth residual currents . So it is names as " universal current-sensitive RCCB", which means it could be used for the widest variety of applications ,these are always also designed for use under harsh ambient conditions.
