Contactor CTX3 4P 500A AC1 100-240V AC/DC 416506

Power and Reliability in Motor Control

The CTX3 4P 500A contactor is a reliable solution for controlling motors and other loads requiring high power. Designed by LEGRAND, this four-pole contactor with a rated current of 500A (AC1) and 400A (AC3) provides effective and safe circuit switching. Its versatility stems from the ability to be powered by both AC and DC voltage in the range of 100-240V, making it an ideal choice for a wide range of industrial and commercial applications.

Construction and Operating Parameters

The contactor's construction is based on solid screw connections of the main contacts, guaranteeing stability and minimizing the risk of loosening connections during operation. It has 4 main normally closed contacts and 2 auxiliary contacts, both normally open and normally closed, allowing for flexible configuration of control circuits. The rated power for AC-3 is as high as 200 kW at 400V, confirming its ability to handle demanding applications. A wide range of control voltages (85-264V AC/DC) increases its compatibility with various control systems.

Application and Benefits

Contactors from the CTX3 series are used in controlling motors, industrial lighting, ventilation systems and other loads requiring reliable switching of electrical circuits. Thanks to its construction and parameters, this contactor is particularly useful in applications requiring frequent switching under heavy load. It is worth noting the versatility of the control voltage – the device can be powered by both alternating and direct current, simplifying installation and reducing storage costs of different models. Additionally, the presence of auxiliary contacts allows for easy integration with signaling and protection systems.
