Contactor CTX3 3P 630A 2NO2NC 200V-240V AC/DC 416346

The powerful heart of your installation – CTX3 630A contactor

This three-pole contactor from the CTX3 series by Legrand is a reliable element for controlling electrical circuits with high loads. Designed to operate in demanding industrial and commercial conditions, it provides effective and safe circuit switching. Its solid construction and high technical parameters make it an ideal solution for both professional installers and end-users looking for a long-lasting and efficient solution.

Performance and versatility in one device

The CTX3 630A contactor stands out with its high rated power for AC-3, reaching as much as 330 kW, allowing control of even very large motors. Rated current of 630A at AC-3 (400V) and 660A at AC-1 (400V) guarantees stable operation in various applications. Contact configuration – 3 main normally open, 2 auxiliary normally open and 2 normally closed – provides flexibility in building control systems. The possibility of powering with both alternating current (170-264V AC) and direct current (170-242V DC) increases its versatility.

Construction and application

This contactor is designed for a wide range of applications, including controlling electric motors, industrial lighting, ventilation systems and other loads requiring frequent switching on and off. Made of high-quality materials, it ensures long-lasting and trouble-free operation. Screw connection of the main contacts facilitates assembly and ensures a secure connection of the wires. Thanks to its compact size, the contactor easily integrates with the existing electrical infrastructure. It is worth mentioning that the CTX3 series is widely used in industrial applications due to its reliability and durability.
