Full load amperage
The first item to consider is the load, which is measured in amperes. This load amperage is the amount of current required to power your device at the line voltage.
Coil voltage
It is the control voltage applied to the coil. When the coil is energized, the magnetic field will change the position of the main contacts. If a small voltage is applied to the coil, the power contact will undergo a continuous vibration pull-down in a short time.
The number of main contacts
The power contactor is available in 1-pole, 2-pole, 3-pole or 4-pole versions. The appropriate contactor should be selected according to the phase number of the load.
