Cutler Hammer-Eaton CN15BN3AB 120V 3 N/O Poles,1 N/O Aux

The Cutler Hammer-Eaton CN15BN3AB is a 120-volt contactor that is used in many electrical systems, including HVAC equipment. It controls the flow of electricity using an electromagnet, much like a switch. The inside coil of the contactor energizes and draws in contacts to link circuits. It is useful in HVAC systems because of its switching ability, which allows it to control the power to parts like fans, motors, and compressors. Three "normally open" poles on the CN15BN3AB stay separated until the coil is activated. It also has one N/O auxiliary pole, which provides an additional circuit for signaling or control. Benefits of this contractor include space-saving design, dependable switching, and effective power distribution, which make it an adaptable option for a range of HVAC applications.
