Contactor 5.5KW, 400V, 12A (AC3), 25A (AC1), 3P+1NO/1NC, 220V AC Coil
A contactor is a special type of relay used for switching an electrical circuit on or off.
They are most commonly used with electric motors and lighting applications.
When your thermostat wants to start a cooling cycle, a small voltage is sent to the contactors that tells them to lower into the “down” position.
This allows electricity to flow to your air conditioner’s parts so that they can operate.
