Why Choose the ABB E290-16-11/12 Latching Relay?
The ABB E290-16-11/12 is a compact and reliable electromechanical latching relay designed for energy-efficient switching of lighting and other compatible electrical loads. As part of the ABB E290 latching relay series, it combines a 16 A rated current with one normally open and one normally closed contact and a 12 V AC control coil.
The E290 uses an impulse-operated mechanical latching mechanism that changes the contact state whenever a control impulse is applied to the coil. After switching, the contacts remain mechanically latched without requiring continuous coil energisation. A front operating lever also permits manual operation while providing a visible indication of the contact state.
With a 16 A rated current, 250 V AC rated operational voltage, 12 V AC control voltage and 1NO+1NC contact configuration, the E290-16-11/12 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 E290-16-11/12 change their contact state each time an electrical impulse is applied to the control coil. The internal mechanical mechanism then retains the new contact position without continuous coil energisation until the next control impulse is received.
This switching principle is particularly useful for lighting circuits controlled from one or more normally open push-buttons. The combination of one normally open and one normally closed contact provides additional circuit flexibility, while the 12 V AC coil makes the E290-16-11/12 suitable for compatible low-voltage control 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.
