GE CT12CUF2K10A Three-phase AC contactor

Product Description

GE CT12CUF2K10A is a 3-phase AC contactor from GE CT12 series, designed for switching and control of industrial motors and electrical loads. This model has a rated operational current of 10A with one normally open auxiliary contact. Adopting modular construction and DIN rail mounting, it is rated for AC-3 motor duty. It features stable arc extinction, high shock resistance and long service life. It can be matched with thermal overload relays for motor overload protection, widely used in control cabinets and automation systems as standard low-voltage component for motor control and power distribution.
