Product Description

Application

CJX2-F series AC contactors are designed for use in 50Hz or 60Hz circuits. When equipped with a special coil, they are compatible with frequencies ranging from 40Hz to 400Hz, supporting voltages up to 660V and currents up to 630A. These contactors are primarily used for making and breaking main circuits, as well as for the frequent starting and control of electric motors.
They can be integrated with various relays to control diverse electrical equipment and circuits. By adding auxiliary contact groups, pneumatic time-delay heads, and mechanical interlocks, they can form star-delta starters or reversible contactors. When combined with a thermal relay, they function as a magnetic starter.

Features

Featuring a fine and compact structure with functional molding, these contactors utilize a coordinated assembly stereoscopic layout. The triple-triad wiring structure is of a linear motion type, and the contacts feature double-breaking points for enhanced reliability. Mechanical interlock mechanisms can be added between two units to create a reversible shift contactor system.
