## Long description

The Relpol RUO400-3014-28-1220 is a robust 4-pole industrial relay engineered for demanding electrical control environments. Designed to provide consistent switching performance, this component operates with a 220V DC coil voltage and utilizes high-grade AgSnO2 contact material. Its construction ensures reliable signal transmission and long-term operational stability in professional automation systems.
Advantages
This industrial relay offers exceptional durability due to its specialized silver-tin oxide contacts, which are highly resistant to welding and electrical erosion. The 4-pole configuration allows for versatile circuit management, enabling the simultaneous control of multiple independent electrical paths. Its compact design and standardized mounting interface facilitate straightforward integration into existing control panels and electrical cabinets, while the IP40 rating provides protection against solid objects, ensuring reliable performance in controlled indoor environments.
Suitable for
Industrial automation and control systems
Power distribution and signal switching
Manufacturing machinery and production lines
Electrical panel building and maintenance
When it may not be suitable
This relay is not intended for outdoor use or environments exposed to moisture, dust, or corrosive gases, as the IP40 rating does not provide protection against liquids or fine particulates. It is also not suitable for high-current power switching applications that exceed the rated contact capacity of the device.
Key specifications
Configuration: 4-pole (4P)
Coil voltage: 220V DC
Contact material: AgSnO2 (Silver-tin oxide)
Protection rating: IP40
How to use
Installation should be performed by qualified personnel in accordance with local electrical regulations. Ensure the coil voltage matches your control circuit output of 220V DC before connection. The relay should be securely mounted within an enclosure that protects it from environmental contaminants. Once mounted, connect the control wires to the coil terminals and the load wires to the appropriate contact terminals, ensuring that all connections are tightened to the manufacturer's specified torque to prevent overheating.
What to consider before purchase
Verify that your control system provides a 220V DC supply for the coil.
Ensure the installation environment meets the IP40 protection requirements.
Check that the load requirements are within the specified contact ratings.
Confirm the physical space availability in your control cabinet for the relay dimensions.
Usage recommendations
Regularly inspect the relay terminals for signs of oxidation or loose connections during scheduled maintenance intervals. Avoid exceeding the rated switching cycles to maintain the longevity of the AgSnO2 contacts.
