Contactor CTX3 3P 65A 2NO2NC 230V AC 416166

3-Pole Contactor – Reliable Circuit Control

The CTX3 contactor is a robust solution for frequent switching of electrical circuits. Designed by LEGRAND, this 3-pole contactor with a rated current of 65A is perfect for applications requiring high reliability and durability. Equipped with three normally open (NO) main contacts and two normally open (NO) and two normally closed (NC) auxiliary contacts, it provides flexibility in control circuit configuration.

Power and Performance for Professional Installations

This model stands out from the competition thanks to its operating parameters. The rated operating power for AC-3 is as high as 30 kW at 400V, and the rated current Ie for AC-3 is 65A. This makes the contactor ideal for controlling electric motors, heaters and other devices with high power consumption. The rated operating current for AC-1 at 400V is 100A, confirming its versatility. A control voltage of 230V AC (50/60 Hz) makes it compatible with most standard electrical installations.

Construction and Application

The CTX3 contactor is characterized by a modular design, which facilitates its installation and integration with other system control elements. The connection of the main contacts is made using cable lugs, which ensures a secure and durable connection of the wires. Designed to operate with AC voltage, this contactor finds application in:

• Industrial electrical installations: Control of motors, pumps, fans and other devices.
• Commercial construction: HVAC systems, lighting, building automation.
• Home applications: Advanced home automation systems requiring high reliability.
• Electrical switchboards: As a protective and control element for circuits.

Additionally, this contactor has a rated operating power for AC-4 at 22 kW with a rated current of 47A, making it suitable for applications requiring frequent switching under load – such as controlling cranes or hydraulic presses. The construction with three NO main contacts allows for simultaneous switching of three phases of the circuit, ensuring efficient control of three-phase devices.
