Description
The Schneider Electric (Square D) LC1D40F7 3-Pole Contactor with a current rating of 40A and a supply voltage of 110VAC. It is the electronic operated switch used for making or breaking an electrical circuit periodically. The 110VAC is applied to the coil and the contactors internal contacts close to enable current to flow through the three poles. This makes it suitable for use in controlling motors and resistive loads in HVAC systems such as air conditioners and heat pumps. The advantages of using relays include switching, longer equipment used to regulate high inrush currents, and safety because the high power circuits can be controlled remotely.
