Schneider Electric Acti9 iCTK50r Modular Contactor, 25A, 2NO, 230/240V AC, Manual Control

The Schneider Electric Acti9 iCTK50r is a high-performance modular contactor engineered for the reliable switching of electrical circuits in residential, commercial, and industrial environments. With a rated current of 25A and a 2NO contact configuration, this device is optimized for managing power distribution and building automation tasks. It operates seamlessly on 230/240V AC networks at 50/60Hz, providing a robust solution for controlling various electrical loads. A standout feature of this model is the integrated manual control switch, which allows users to override automatic functions and perform local switching directly at the distribution board.

Advantages

This modular contactor offers exceptional reliability and durability, consistent with the high standards of the Acti9 series. The inclusion of a manual control lever simplifies maintenance and troubleshooting, as it enables operators to test or isolate circuits without needing to adjust upstream control signals. Its compact modular design ensures easy installation on standard DIN rails, saving valuable space in electrical enclosures. Furthermore, the device is designed to handle frequent switching operations, making it an ideal choice for demanding applications where longevity and consistent performance are required.

Suitable for

• Control of lighting circuits in commercial buildings
• Management of electric heating systems
• Operation of ventilation and air conditioning units
• Manual override of automated electrical loads

When it may not be suitable

This contactor is not designed for applications requiring more than two poles or specific auxiliary contact expansions, as it does not support additional contact blocks. It is also not suitable for high-voltage DC switching or environments where the current load consistently exceeds the 25A rating.

Key specifications

• Rated operational current: 25A
• Contact configuration: 2 Normally Open (2NO)
• Operational voltage: 230/240V AC
• Frequency: 50/60Hz
• Control type: Manual and automatic
• Mounting: DIN rail

How to use

The device should be installed by a qualified professional in a standard electrical distribution board on a DIN rail. Once mounted, connect the power supply and the load cables to the designated terminals according to the wiring diagram. The manual control switch on the front of the unit allows for immediate local operation; toggle the switch to manually engage or disengage the contacts as needed. Ensure that the control circuit is correctly wired to the coil terminals to enable automatic operation via external sensors or timers.

What to consider before purchase

• Verify that the 25A current rating is sufficient for your specific load requirements.
• Ensure the 2NO contact configuration meets your circuit design needs.
• Confirm that the 230/240V AC voltage matches your local power supply.
• Check available space in your distribution board for modular DIN rail equipment.

Usage recommendations: Regularly inspect the contactor for signs of wear or overheating, especially in high-frequency switching applications. Ensure that all terminal connections are tightened to the manufacturer's specified torque to prevent loose contacts and potential electrical faults.
