From the supplier
This series contactor is mainly applicable to a line of AC 50Hz or 60Hz,rated working voltage up to 600V and rated working current up to 90A,used to close or and to switch off the line.It complines to IEC947-4-1 standard.
Why do air conditioners need special contactors
1. Under normal circumstances, the three-phase load current and the ground leakage current are basically balanced. The phasor sum of the primary coil current flowing through the transformer is about zero, that is, the total magnetic flux generated by it in the iron core is zero, and the zero sequence transformer No output from secondary coil.
2. When an electric shock occurs, the electric shock current forms a loop through the ground, that is, a zero sequence current is generated. This current does not flow back through the primary coil of the transformer, which breaks the balance, so there is zero-sequence magnetic flux in the iron core, which causes the secondary coil to output a signal. This signal is judged by the amplifying and comparing elements. If it reaches a predetermined action value, it will send an execution signal to the actuator to trip and cut off the power supply.
3. It can be seen from the working principle that when the impedance difference between the three relative grounds is large, the phasor of the three relative ground leakage currents and the action value of the protector will be reached, the circuit breaker will be tripped or not powered. At the same time, the phases of the three-phase leakage current and the electric shock current are inconsistent or reversed, which will reduce the sensitivity of the protector.
