Construction and Feature

BFRC-10o/B for type A and in addition for smooth D.C residual currents, residual D.Ccurrents which may result from rectifying circuits and high frequency A.C residual currents BFRC-10o/B tripping conditions for frequencies up to IkHz are defined.It provide: Protection in the event of continuous fault current on three-phase networks generated by: Controllers and variable speed drives Battery charges and inverters Backed-up power supplies
