。it is suitable for frequency 50/60Hz,rated insulation voltage up to 1000V
。rated opera tion current 9~300A under AC3 duty.
。It is mainly used for making/breaking electric circuits at a long distance & for frequent starting/stopping & controlling A.C.Motors.t
。 is used in combination with thermal relay to compose a magnetic motor starter
。The contactor has install current –limited resistor, can restrain the switch on inrush current .
。The contactor is direct-acting and double-break structure, operation flexible, conveniently manual operation inspect.
。The contactor connection terminal has insulating boot , very safe.
。The contactor can be install by screw, also can install in the bus bar.
。Voltage across zero put on , current across zero cut off , no harmonic current, do not appear over voltage.
。Lower power dissipation after power on , do not need add air-cooling fin.
。Do not produce harmonic , do not need series connecting reactor .
。Put in signal isolated with switching optical , high EMC protection , good capacity of resisting disturbance.
。Can match with our dynamic compensation controller.
