Why Choose the ABB E290-16-10/230 Latching Relay?
The ABB E290-16-10/230 is a compact and reliable electromechanical latching relay designed for energy-efficient switching of lighting and other suitable electrical loads from multiple control points. As part of the ABB E290 latching relay series, it combines a 16 A switching rating with one normally open contact and a 230 V AC / 110 V DC control coil.
Unlike a conventional monostable relay, the E290 uses a mechanical latching mechanism that changes contact state each time a control impulse is applied. The coil is energised only briefly during switching, after which the contacts remain mechanically latched in their new position without continuous coil power. This operating principle makes the E290 particularly suitable for efficient lighting control using normally open push-buttons.
With a 16 A rated current, 250 V AC rated operational voltage, 230 V AC / 110 V DC control voltage and 1NO contact configuration, the E290-16-10/230 is ideal for lighting circuits in residential, commercial, public and industrial buildings. Its compact 18 mm DIN rail format enables straightforward installation in modular distribution boards and control panels.

Energy-Efficient Impulse Switching for Lighting Control
Latching relays such as the ABB E290-16-10/230 change their contact state each time a short electrical impulse is applied to the control coil. The internal mechanical mechanism then holds the contact securely in that position until the next control impulse, eliminating the need to keep the coil continuously energised.
This switching principle is particularly useful where lighting needs to be controlled from three or more locations using normally open push-buttons. The E290 series is suitable for private homes, factory premises, commercial and public buildings and industrial plants, providing a simple and efficient alternative to complex multi-way lighting wiring.
Typical Applications
- Multi-point lighting control systems.
- Staircase and corridor lighting.
- Residential electrical installations.
- Commercial and public building lighting.
- Factory and industrial lighting systems.
- DIN rail distribution boards and control panels.
