Reasons to use power contactors

The power contactors are mainly made up of the following elements that justify their necessary use in all our equipments.

*Auxiliary contacts:
The auxiliary contacts are acting at the same time of the main contacts, responsible for the opening and closing the auxiliary circuits and the control circuit of the contactor; They can be Normally opened (NO) or normally closed (NC) depending on the use wanted for the device.
They are essential not to overload (in Amperes) the breaker of the auxiliary devices like for example a chlorinator, and to let the filtration working in order to still supply the chlorinator.

*Extinguishing chambers or spark arrestors:
The extinguishing chambers and spark arrestors are the enclosures where are located the contacts. They make the breaking arc (short but high temperature current flow that happens when opening the contacts to cut the pump supply) longer: it is divided and then vanish, preventing over temperature when opening the contacts.
If we did not put contactors in our devices, the component that directly disconnect the pump would receive all the intensity of the breaking arc whether it is a programmer or a radio control… which would reduce the devices life expectancy as they are no prepared to receive such a strong current.
Though it is a little bit more expensive to integrate contactors to our devices, we consider that it is essential to reduce the braking down risks and to increase the device life expectancy.

*Total disconnection of the supply:
If there are no contactors, only a phase of the power supply is cut so the external element (The pump) which is controlled by the device will have an active phase. If the installer or the person in charge of the maintenance, think the pump is off and touch it, there is a risk of electrocution.
With the contactors we guarantee a 100% disconnection of the power supply until the pump, eliminating the accident risks.
