Cutler Hammer-Eaton CN15GN3AB 3-Pole Contactor Coil 45A 120V

The Cutler-Hammer Eaton CN15GN3AB is a 120V, 45 amp, 3-pole contactor with an auxiliary contact intended for use in a variety of HVAC applications. When a control signal is supplied, it operates as an electromechanical switch that regulates high power by opening or closing internal contacts. An electromagnetic coil is used to accomplish this switching function; it produces a magnetic field in response to a signal. The contacts physically open or close in response to an activation of the magnetic field, which stops or resumes the flow of current to the attached load.  The Cutler-Hammer Eaton CN15GN3AB essentially serves as a safety switch and control mechanism for high-current HVAC system parts such as pumps, compressors, and fan motors.
