An air conditioner contactor or AC contactor (Motor Starter – Thyristor) is a single pole double-throw (SPDT) and an energy-efficient electrical switching device that can switch an electrical circuit and motors on and off in motorized applications such as elevators, escalators, lighting systems, equipment such as fuse boxes and electrical systems found in commercial buildings like schools, hospitals and offices, and residential buildings. It provides a highly efficient and reliable method to control electric motors by providing low-voltage/high-current contacts to direct current from the power source such as a transformer, rectifier, or power supply.
AC Contactors consist of a coil wire, also called the armature, which performs the actual switching functions of the device by switching contacts and controlling the voltage source or the flow of the electricity. Also, a pair of switching elements (Usually electromagnetic in nature) mounted on a single shaft is known as the “The Contractor Shaft”. The magnetic field produced by the coil of wire is to complete or break the electric current or circuit.
Types Of AC Contactors
AC Contactors come in many different styles with many different features, but they all have this in common: reliable power control for your equipment. This is done by switching voltages ranging from 0 to 400 volts. They can handle rates in different voltage classes (HV – High Voltage, MV- Medium Voltage, V- Low Voltage).
Examples of AC Contactors
For example, they are used for tripping in an air condition circuit. The Ac Contactors close to the furnace or the air handler are extremely important HVAC parts of the HVAC system. That is because the air conditioner contactor is used to run or not run the air handler. They can be configured simply or very complex. An AC contactor has two coils of wire: one is activated by the thermostat and one is activated by the AC unit. When either one of those “ON” coils gets cold it closes in the unit and completes a circuit to allow electricity to flow which turns on your air conditioner.
