Product Description

Application

CJX2-F series AC contactors (the following is called a contactor) are used in 50Hz or 60Hz circuits. If equipped with a special coil, they can be used in circuits with a frequency of 40-400Hz, with a voltage up to 660V and a current up to 630A. They are used for making and breaking the main circuit, as well as for frequently starting and controlling motors.

They can be combined with general electrical equipment such as various relays, which can be used to control various electrical equipment, motors, and circuits. With auxiliary contact groups, pneumatic time-delay heads, and mechanical interlocks, they can also form mechanically interlocked contactors and star-delta starters. When combined with a thermal relay, they can form a magnetic starter.

Type & Meaning

CJ X2 - F □ 1 2 3 4

1	AC contactor
2	minature
