Why Choose the ABB E290-16-10/12 Latching Relay?
The ABB E290-16-10/12 is a compact and reliable electromechanical latching relay designed for impulse-controlled switching in lighting, building control and electrical distribution applications. As part of the ABB E290 latching relay series, it combines a 16 A rated switching current with one normally open contact and a 12 V AC / 6 V DC control coil.
Unlike a conventional monostable relay, the E290 uses an impulse-operated mechanical latching mechanism to change and retain its contact state. A short control pulse switches the relay, after which the contact remains in its selected position without continuous coil energisation until the next switching impulse is received.
With a 16 A rated current, 250 V AC rated operating voltage and 12 V AC / 6 V DC control voltage, the E290-16-10/12 is well suited to low-voltage push-button control circuits. Its compact 18 mm modular design enables straightforward installation on DIN rail inside electrical distribution boards and control panels.

Efficient Impulse Switching for Electrical Installations
Latching relays such as the ABB E290 use short electrical control impulses to change their switching state. The internal mechanical latching mechanism retains the contact position after the control pulse ends, eliminating the need for continuous coil energisation and keeping the selected state until another impulse is applied.
This operating principle makes the E290 series particularly useful for lighting and building-control circuits operated from multiple locations. Push-buttons can provide switching impulses from different points while the centrally mounted relay performs the actual load switching inside the electrical distribution board.
Typical Applications
- Lighting circuits controlled from multiple locations.
- Residential and commercial building installations.
- Electrical distribution boards.
- Low-voltage impulse push-button control circuits.
- Industrial and commercial control panels.
- DIN rail mounted automation and switching systems.
