Contactor CTX3 3P 85A 2NO2NC 24V DC 416201

3-Pole Contactor – Reliable Circuit Control

This 3-pole contactor from the CTX3 series by Legrand is a robust solution for frequent switching of electrical circuits. Designed to operate with a DC 24V voltage, it is perfect for industrial applications and building automation. Its construction ensures high reliability and long life, which translates to minimizing downtime and maintenance costs.

Performance and Technical Specifications

The CTX3 3P 85A contactor is characterized by high operating parameters. The rated operating power for AC-3 is as high as 45 kW with a current of 85A, allowing control of even demanding loads. Additionally, the rated current AC-1 is 135A, and for AC-4 – 62A. The construction with three screw-type main contacts (NO) and two auxiliary normally open (NO) and normally closed (NC) contacts provides flexibility in control circuit configuration. The control voltage DC is in the range of 20.4 - 26.4V, ensuring compatibility with popular control systems. Connection of the main contacts is done using cable lugs, which simplifies installation and ensures a secure connection.
