## Summary description

The Eaton CMUC230/25-04 is a high-quality modular contactor designed for reliable switching of electrical loads. It features a 25A rated operational current and 4 normally closed (NC) contacts. Operating on a 230V AC/DC control voltage, this device is ideal for industrial and residential automation systems, providing efficient control of lighting, heating, and ventilation equipment in modular distribution boards.

## Long description

The Eaton CMUC230/25-04 is a high-performance modular contactor engineered for the precise and reliable switching of electrical circuits. Designed for integration into standard modular distribution boards, this device manages electrical loads with a rated operational current of 25A. It is equipped with four normally closed (NC) contacts, ensuring that the circuit remains closed in its default state and opens only when the control signal is applied. With a versatile 230V AC/DC control voltage, this contactor offers flexibility for various automation applications in both residential and industrial environments.
Advantages
This modular contactor stands out due to its robust construction and high operational reliability, which are hallmarks of Eaton engineering. The device is specifically designed to operate silently, making it an excellent choice for environments where noise reduction is a priority, such as residential buildings or office spaces. Its compact modular design allows for seamless installation on standard DIN rails, saving valuable space in electrical cabinets. Furthermore, the dual compatibility with AC and DC control voltages simplifies inventory management and provides greater flexibility for system designers and installers.
Suitable for
Control of lighting systems in residential and commercial buildings
Switching of heating and ventilation equipment
Automation of electrical loads in modular distribution boards
Integration into building management systems
When it may not be suitable
This contactor is not intended for applications requiring normally open (NO) contacts, as it is specifically configured with four normally closed (NC) contacts. Additionally, it should not be used in environments that exceed its rated operational current of 25A or in conditions where the control voltage deviates from the specified 230V AC/DC range.
Key specifications
Rated operational current: 25A
Contact configuration: 4 normally closed (NC)
Control voltage: 230V AC/DC
Mounting type: DIN rail
Design: Modular
How to use
Installation should be performed by a qualified electrician in accordance with local electrical regulations. The contactor is designed to be snapped onto a standard 35mm DIN rail within a distribution board. Ensure that the power supply is disconnected before beginning the installation. Connect the control circuit wires to the coil terminals and the load circuit wires to the power terminals, ensuring all connections are tightened to the manufacturer's specified torque to prevent overheating. Once installed, verify the operation by applying the control voltage to ensure the contacts open as expected.
What to consider before purchase
Verify that the 4NC contact configuration matches your specific circuit requirements.
Ensure the 25A current rating is sufficient for the load you intend to switch.
Confirm that your control system provides a 230V AC/DC signal.
Check the available space in your distribution board for modular mounting.
Usage recommendations
Regularly inspect the contactor terminals for tightness and ensure the device is kept free from dust and moisture to maintain optimal performance and longevity.
