Contactor CTX3 3P 100A 2NO2NC 230V AC 416226

Reliable circuit control – CTX3 100A contactor

The CTX3 100A contactor is a component designed for safe and efficient control of electrical circuits in industrial and commercial installations. Designed by Legrand, a manufacturer of established electrical solutions, this three-pole contactor provides reliable operation in demanding conditions. Its modular design simplifies integration with other system components, and high efficiency guarantees optimal energy utilization.

Parameters and application

This contactor, with a rated current of 100A, is perfect for applications requiring frequent switching of the load. The rated operating power for AC-3 is as high as 55 kW, making it suitable for controlling motors with significant power. It has three main normally closed contacts, two normally closed auxiliary contacts and two normally open contacts, providing great flexibility in configuring control circuits. Cable terminals ensure convenient and secure connection of wires. The control voltage of 230V AC is a standard in most installations.

• Thanks to the AC-3 rated current of 105A and AC-1 – 160A, the contactor provides a power reserve and long-term trouble-free operation.
• The availability of two normally closed (2NO) and two normally open (2NC) auxiliary contacts allows for the implementation of complex control and signaling functions.
• Modular design simplifies expansion and modification of the installation.
• Ideal for controlling motors, electric heaters and other loads requiring high reliability and frequent switching.
• Compliance with safety standards provides protection against overload and short circuit.

Construction and benefits for professionals

The CTX3 contactor is characterized by a solid construction ensuring long life and resistance to mechanical damage. The modular design simplifies diagnostics and replacement of elements in the event of a failure – which translates into shorter downtime of the installation. Therefore, installers can count on quick installation, easy configuration and minimal system maintenance costs. A wide range of control voltages (195.5…253 V AC) increases the versatility of the device and allows it to be used in different types of installations. Characteristic C allows it to react more slowly to short current surges, therefore it tolerates starting devices with a motor well.
