Why Choose the ABB E290-32-10/8 Latch Relay?
The ABB E290-32-10/8 is a compact and reliable electromechanical latching relay designed for pulse-operated switching of electrical loads in building, commercial and industrial installations. As part of the ABB E290 mechanical latching relay series, it combines a high 32 A rated current with one normally open contact and a space-saving modular DIN rail format.
The relay is activated by control pulses and mechanically retains its selected switching state without requiring continuous coil energisation. This makes the E290 series particularly suitable for energy-optimised lighting control systems where a circuit needs to be operated from several pushbutton locations.
With a 32 A rated current, 1NO contact configuration and 8 V AC coil control voltage, the E290-32-10/8 provides dependable switching for low-voltage control applications. Its compact 18 mm width enables straightforward installation on standard 35 mm DIN rails in main and sub-distribution systems.

Efficient Pulse-Operated Switching Control
Latching relays such as the ABB E290 use control pulses to change and retain their switching state. This operating principle provides an efficient method of controlling electrical loads without requiring the relay coil to remain continuously energised after switching.
The E290 series is designed for direct installation in main and sub-distribution systems and is particularly useful where lighting needs to be controlled from multiple locations. Its modular construction and standard DIN rail mounting make it a practical solution for modern electrical distribution and building-control installations.
Typical Applications
- Lighting control from multiple pushbutton locations.
- Main and sub-distribution systems.
- Commercial and industrial building installations.
- Electrical load switching and control circuits.
- DIN rail mounted electrical control panels.
- Energy-optimised pulse-operated lighting control.
