Contactor CTX3 4P 420A AC1 100-240V AC/DC 416496

Power and Reliability in Motor Control

The CTX3 4P 420A contactor is a reliable solution for controlling electrical loads, especially motors. Designed by LEGRAND, this four-pole contactor with a rated current of 420A (AC1) and 330A (AC3) provides safe and efficient circuit switching. Its versatility comes from the ability to power both AC and DC voltage in the range of 100-240V, making it an ideal choice for various industrial and commercial applications.

Construction and Application

This contactor is widely used in motor control, industrial lighting, ventilation systems and other loads requiring frequent connection and disconnection of electrical circuits. The contactor design with four main normally closed contacts and two auxiliary normally open and normally closed contacts allows for flexible adaptation to specific installation needs. Screw connection of the main contacts ensures a secure and durable connection of the wires.

Key Features and Benefits

• High rated power: The rated power for AC-3 is as high as 160 kW, allowing control of even large loads.
• Wide control voltage range: The ability to power both AC (85-264V) and DC (85-242V) voltage increases installation flexibility.
• Versatility: Four normally closed main contacts provide reliable circuit switching. Additional auxiliary contacts expand the functionality of the contactor, enabling the implementation of more complex control systems.
• Solid construction: LEGRAND CTX3 series contactors are known for their high quality workmanship and durability, which guarantees a long service life even in harsh working conditions.
• Safety: Provides effective protection of the installation against overload and short circuit - like most circuit breakers in this class.
• Universal mounting: Compact dimensions make it easy to mount in electrical panels.

Thanks to its reliability and versatility, the CTX3 contactor is an ideal choice for both professional installers and end-users looking for a solid solution for controlling electrical loads.
