Why Choose the ABB E290-16-11/24 Latching Relay?
The ABB E290-16-11/24 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 and one normally closed contact and a 24 V AC / 12 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 contacts remain in their 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 24 V AC / 12 V DC control voltage, the E290-16-11/24 provides complementary 1NO/1NC switching for low-voltage control systems. Its compact modular format is designed for straightforward DIN rail installation in electrical distribution boards and control panels.

Efficient Impulse Switching for Electrical Installations
Latching relays such as the ABB E290 use short electrical impulses to change their switching state. The internal mechanical mechanism retains the contact position after the control pulse ends, reducing coil energisation and allowing the relay to remain in its selected state until another impulse is applied.
The 1NO/1NC configuration of the E290-16-11/24 provides complementary contact functions, allowing one circuit to close while another opens when the relay changes state. This makes it suitable for lighting control, signalling and other electrical applications requiring opposing switching functions from a single impulse-operated device.
Typical Applications
- Lighting circuits controlled from multiple locations.
- Residential and commercial building installations.
- Electrical distribution boards.
- Low-voltage impulse push-button control circuits.
- Complementary load and signalling circuits.
- DIN rail mounted automation and switching systems.
