Why Choose the ABB E290-16-10/115 Latching Relay?
The ABB E290-16-10/115 is a compact and reliable electromechanical latching relay designed for impulse-controlled switching in building installations, lighting circuits and electrical control systems. As part of the ABB E290 latching relay series, it combines a 16 A rated switching current with one normally open contact and a 115 V AC / 60 V DC control coil.
Unlike a conventional monostable relay, the E290 changes its mechanically latched contact position each time a short control pulse is applied to the coil. The contact remains in its selected state without continuous coil energisation until the next impulse is received, providing efficient switching where loads need to be controlled from one or multiple push-buttons.
With a 16 A rated current, 250 V AC rated contact voltage and 115 V AC / 60 V DC coil control voltage, the E290-16-10/115 is particularly suited to lighting and building-control circuits. Its compact 18 mm width occupies one DIN module, while the front operating lever permits manual actuation and provides a clear indication of contact status.

- Front lever for manual operation and contact-position indication.
- DIN rail mounting with screw-terminal connections.
Efficient Impulse Switching for Electrical Installations
Latching relays such as the ABB E290 switch their contacts whenever an electrical impulse is applied to the control coil. The internal mechanical latching mechanism then holds the selected contact position without requiring the coil to remain continuously energised, with the next control pulse changing the relay back to its alternate state.
This operating principle makes the E290 series particularly useful for lighting circuits controlled from multiple locations. Normally open push-buttons can provide control impulses from different points, while the relay performs the actual load switching centrally within the electrical distribution board.
Typical Applications
- Lighting circuits controlled from multiple locations.
- Residential and commercial building installations.
- Electrical distribution boards.
- Impulse push-button control circuits.
- Industrial and commercial control panels.
- DIN rail mounted automation and switching systems.

Frequently Asked Questions
What is the ABB E290-16-10/115 used for?
The ABB E290-16-10/115 is an electromechanical latching relay used for impulse-controlled switching of electrical loads, particularly lighting circuits operated from one or multiple push-button locations.
What is the current rating of the E290-16-10/115?
The relay has a rated switching current of 16 A and a rated contact voltage of 250 V AC.
What control voltage does this latching relay require?
The E290-16-10/115 is designed for a 115 V AC / 60 V DC control voltage.
What contact configuration does the E290-16-10/115 have?
This model has one normally open (1NO) contact that changes state when a control impulse is applied to the relay coil.
How does the ABB E290 latching relay operate?
A short electrical pulse energises the coil and changes the mechanically latched contact position. The contact remains in that position without continuous coil power until another control pulse switches it again.
