Why Choose the ABB E290-16-11/230 Latching Relay?
The ABB E290-16-11/230 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 and one normally closed contact and a 230 V AC / 110 V DC control coil.
Unlike a conventional monostable relay, the E290 uses an impulse-operated mechanical latching mechanism. Each brief control pulse changes the contact state, after which the contacts remain mechanically latched without continuous coil energisation. This operating principle provides efficient switching and makes the relay particularly suitable for lighting circuits controlled from multiple 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+1NC contact configuration, the E290-16-11/230 provides complementary switching functions for residential, commercial and industrial installations. Its compact 18 mm DIN rail format enables straightforward integration into modular distribution boards and control panels.

Energy-Efficient Impulse Switching for Lighting Control
Latching relays such as the ABB E290-16-11/230 change their contact state each time a short electrical impulse is applied to the control coil. The internal mechanical mechanism then holds the contacts securely in their new position without continuous coil energisation until the next control impulse is received.
This switching principle is particularly useful where lighting needs to be controlled from three or more locations using normally open push-buttons. The combination of one normally open and one normally closed contact provides additional control flexibility, while the compact DIN rail construction makes the E290-16-11/230 suitable for residential, commercial, public-building and industrial distribution systems.
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.
