Why Choose the ABB E290-32-10/12 Latch Relay?
The ABB E290-32-10/12 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 latching relay series, it combines a high 32 A rated current with a normally open contact and a space-saving modular DIN rail format.
The relay changes the state of its contact each time a control pulse is applied to the coil through normally open pushbuttons, allowing a load to be controlled conveniently from one or more locations. Its mechanically latched operation means the selected contact state is retained without continuous coil energisation, while a front operating lever enables manual actuation and provides visual indication of the contact state.
With a 32 A rated current, 1NO contact configuration and 12 V AC coil control voltage, the E290-32-10/12 is particularly suitable for lighting and electrical load-control circuits. Its compact 18 mm width enables straightforward installation on standard DIN rails in main and sub-distribution boards.

Efficient Pulse-Operated Switching Control
Latching relays such as the ABB E290 change their contact state whenever an electrical pulse is sent to the coil through a normally open pushbutton. The mechanically latched switching mechanism retains the selected state after the control pulse has ended, making these devices particularly useful for efficient remote load control.
The E290 series is designed especially for applications such as lighting circuits that need to be operated from one or more locations. Its modular DIN rail construction, manual operating lever and robust electromechanical design provide a practical solution for modern building and electrical distribution installations.
Typical Applications
- Lighting control from multiple pushbutton locations.
- Main and sub-distribution boards.
- Commercial and industrial building installations.
- Electrical load switching and control circuits.
- DIN rail mounted control panels.
- Pulse-operated remote switching systems.
