AC contactor SZRC1-115 ~ 780A Product Details: SZRC1-115 ~ 780 series AC contactor (hereinafter referred to as contactor) for AC 50Hz (or 60Hz) rated working voltage 1000V relay, in AC-3 using the category rated working voltage when 400V, rated current 115A ~ 780A AC circuit for remote making and breaking and frequent starting AC motor control. The contacts can be easily install auxiliary contact group first class or air accessory delay, and with the appropriate thermal overload relay pressure combined into the electromagnetic starter relay to protect the load circuit may happen. Standard: IEC60947-4, GB14048.4, IEC60947-5, GB14048.5. Input and output chokes input and output chokes Features: ◆ the input end of the relay symbol reactors for the drive to suppress the surge voltage and surge current protection of the inverter and the governor, to extend its life and prevent harmonic interference Enter the reactor can be simply understood as: smoothing reactors time relay symbols, when the site selection of voltage instability. ◆ Output reactors for the load side of the inverter, the motor current flows through the reactor. The purpose is to extend the output from long cable compensation capacitive charge reversal currents, the choice away from the inverter when the motor exceeds 100m (ordinary cable).
