Why Choose the ABB E290-32-11/12 Latch Relay?
The ABB E290-32-11/12 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 mechanical latching relay series, it combines a high 32 A rated current with one normally open and one normally closed main contact in a space-saving modular DIN rail format.
The relay changes its contact state each time a control pulse is applied to the coil using normally open pushbuttons, allowing electrical loads to be controlled conveniently from one or more locations. Its mechanically latched operation retains the selected switching state without continuous coil energisation, while the front operating lever provides manual actuation and contact-state indication.
With a 32 A rated current, 1NO + 1NC contact configuration and 12 V AC coil control voltage, the E290-32-11/12 provides dependable switching for low-voltage control systems. Its compact 18 mm width enables straightforward installation in main and sub-distribution boards and other DIN rail control assemblies.

Efficient Pulse-Operated Switching Control
Latching relays such as the ABB E290 switch their contacts whenever an electrical pulse is sent to the coil through a normally open pushbutton. The mechanically latched mechanism retains the selected contact state after the control pulse has ended, providing an efficient method of controlling electrical loads without continuous coil energisation.
The E290 series is particularly suitable for applications such as lighting circuits that need to be controlled from one or more locations. Its modular DIN rail construction, manual operating lever and complementary 1NO + 1NC contacts make the E290-32-11/12 a practical switching solution for modern electrical distribution and building-control 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.
