4 Pole B model RCCB Residual Current Circuit Breaker RCCB , 6KA Smart Circuit Breaker
GENERAL
STID-B RCCB B model is worked on type A and in additon for smooth DC residual currents, residual DC currents that may result from rectifying circuits and high frequency AC residual currents. It protects in the event of contunuous fault current on three phase networks.It usually is used in the field of Recharging Station,Medical Apparatus and Instruments, Controllers and Variable Speed Drives,Batter Charges and Inverters(DC)...STID-B complys with IEC/EN61008 and IEC/EN62423 standard.
