Auxiliary contacts for CTX mini contactors – expand control capabilities

The front 3NO1NC CTX mini auxiliary contacts are a reliable element that expands the functionality of Legrand CTX series contactors. They allow the creation of complex control circuits, status signaling, and provide additional protection. Front-mounted, they are a convenient solution for both installers and end-users who need a flexible and easy-to-configure control system.

Construction and application

These auxiliary contacts are designed for front mounting in CTX mini contactors. Their construction based on screw connections ensures a secure and durable connection of wires. The 3NO (normally open) and 1NC (normally closed) contact configuration allows for the implementation of various functions, such as:

• Device operating status signaling
• Controlling other circuit elements
• Self-holding function implementation
• Creating alarm circuits

They find wide application in industrial automation, lighting control systems, HVAC (heating, ventilation and air conditioning) and other applications requiring reliable control of electrical circuits.
