Eaton CE15CNS3AB Contactor

Eaton CE15CNS3AB is an IEC OPEN, three-pole contactor (3P) in a size C frame designed to switch a three-phase electrical load in industrial control systems. It is equipped with a 120V coil, allowing energization from standard low-voltage control circuits commonly used in electrical panels and control cabinets. The IEC OPEN construction keeps the contacts accessible for connection and testing within typical control enclosures, and the CE15CNS3AB designation communicates its configuration and coil specification at a glance—the three poles, size C frame, and 120V coil—facilitating correct matching with control circuits and installation requirements. In operation, this IEC contactor provides a straightforward means to open or close a three-phase circuit in response to control signals, enabling remote control of three-phase loads within compliant industrial environments. Users select this model when a 3P, size C, 120V coil is required for controlling three-phase power in space-constrained installations.
