ABB E290-16-10/230 Latching Relay 16A 1 NO 230VAC/110VDC

The ABB E290-16-10/230 is a high-performance latching relay engineered for reliable electrical circuit management. This electromechanical device functions by receiving short electrical pulses from impulse buttons, which trigger an internal mechanical latching mechanism to switch the main contacts. Designed for efficiency, it maintains its state mechanically until the next control pulse is received, making it an ideal solution for energy-saving lighting control systems in various environments.

Advantages

This latching relay offers a robust and energy-efficient way to manage lighting circuits, as the coil is only energized briefly during the switching process rather than continuously. Its mechanical interlock system ensures stable operation and long-term reliability, functioning similarly to a ballpoint pen mechanism. The compact design allows for easy integration into standard electrical distribution boards, while the 16A capacity provides sufficient power handling for most residential and commercial lighting applications.

Suitable for

• Lighting control systems in private homes
• Commercial and public building automation
• Industrial plant lighting management
• Multi-point lighting control requiring operation from three or more locations

When it may not be suitable

This device is not intended for applications requiring continuous high-current switching beyond its 16A rating or for circuits that do not utilize impulse-based control signals. It is not suitable for environments where the ambient temperature or electrical noise levels exceed the manufacturer's specified operational limits.

Key specifications

• Rated current: 16A
• Contact configuration: 1 NO (Normally Open)
• Coil voltage: 230V AC / 110V DC
• Operating principle: Electromechanical impulse latching
• Compliance: IEC/EN 61008 standards

How to use

The relay should be installed by a qualified professional within a suitable electrical enclosure. Connect the control circuit to the coil terminals using impulse buttons placed at the desired control locations. When a button is pressed, a brief pulse energizes the coil, causing the internal contacts to latch into the closed position. A subsequent pulse will release the latch, opening the contacts. Ensure that the wiring is correctly sized for the 16A load and that all connections are tightened according to standard electrical safety practices.

What to consider before purchase

• Verify that your control system utilizes impulse buttons rather than standard toggle switches
• Ensure the coil voltage matches your control circuit supply
• Check that the 16A current rating is sufficient for your connected lighting load
• Confirm available space in your distribution board for DIN-rail mounting

Usage recommendations: For optimal performance and longevity, ensure the device is protected from excessive dust and moisture. Regularly inspect the electrical connections during routine maintenance to ensure they remain secure and free from oxidation.
