Eti-Polam R 25-04 Modular Contactor 25A 230V 4NC

The Eti-Polam R 25-04 is a high-quality modular contactor engineered for precise electrical circuit switching in various power distribution environments. Designed to handle a rated current of 25A and a control voltage of 230V, this device provides a reliable solution for managing electrical loads. It is equipped with four normally closed (NC) contacts, ensuring that the circuit remains closed in the default state and opens when the coil is energized. This contactor is built for seamless integration into standard modular distribution boards, offering robust performance and long-term operational stability for both residential and industrial electrical systems.

Advantages

The primary benefit of the Eti-Polam R 25-04 lies in its compact modular design, which allows for efficient space utilization within electrical enclosures. Its construction ensures high switching reliability and durability, minimizing the need for frequent maintenance. The device operates quietly, making it suitable for environments where noise reduction is essential. Furthermore, its standardized dimensions facilitate easy installation on standard DIN rails, ensuring compatibility with a wide range of electrical distribution equipment.

Suitable for

• Residential lighting control systems
• Industrial automation and process control
• Heating and ventilation systems
• Power management in modular distribution boards
• Switching of resistive and inductive loads

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. It is also not suitable for high-voltage industrial power grids exceeding its rated operational voltage or for environments with extreme moisture or corrosive gases that could compromise the internal components.

Key specifications

• Rated current: 25A
• Control voltage: 230V AC
• Contact configuration: 4 normally closed (NC)
• Mounting type: DIN rail
• Design: Modular

How to use

Installation should be performed by a qualified electrician in accordance with local electrical safety regulations. The contactor is designed to be snapped onto a standard 35mm DIN rail within a distribution board. Connect the control circuit wires to the coil terminals and the load circuit wires to the power terminals, ensuring that all connections are tightened to the specified torque to prevent overheating. Once installed, verify the operation of the contacts by applying the control voltage to the coil.

What to consider before purchase

• Verify that the 4NC contact configuration meets your specific circuit requirements.
• Ensure the control voltage of your system matches the 230V rating of the device.
• Check the available space in your distribution board to accommodate the modular width.
• Confirm that the 25A current rating is sufficient for the intended load.

Usage recommendations: Regularly inspect the terminal connections for tightness and ensure the device is kept free of dust and debris to maintain optimal performance and safety over the lifespan of the contactor.
