Why Choose the ABB E290-16-11/115 Latching Relay?
The ABB E290-16-11/115 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 115 V AC / 60 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 makes the relay particularly suitable for lighting circuits controlled from one or more normally open push-buttons.
With a 16 A rated current, 250 V AC switching voltage, 115 V AC / 60 V DC control voltage and 1NO+1NC contact configuration, the E290-16-11/115 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.
Key Advantages

Energy-Efficient Impulse Switching for Lighting Control
Latching relays such as the ABB E290-16-11/115 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 another control impulse changes the state again.
This switching principle is particularly useful where lighting needs to be controlled from multiple locations using normally open push-buttons. The combination of one normally open and one normally closed contact provides additional circuit flexibility, while the compact DIN rail construction makes the E290-16-11/115 suitable for residential, commercial, public-building and industrial distribution systems.
Typical Applications
- Multi-point lighting control systems.
- Staircase and corridor lighting.
- Residential electrical installations.
