Why Choose the ABB E290-32-20/12 Latch Relay?
The ABB E290-32-20/12 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 two normally open contacts and a space-saving modular DIN rail format.
The relay changes its switching state when a control pulse is applied to the coil, allowing electrical loads to be controlled conveniently from one or more pushbutton locations. Its mechanically latched operation retains the selected contact state without continuous coil energisation, making it an efficient solution for lighting control and electrical distribution applications.
With a 32 A rated current, 2NO contact configuration and 12 V AC coil control voltage, the E290-32-20/12 provides dependable switching for low-voltage control systems. Its modular construction enables straightforward installation on standard 35 mm DIN rails in main and sub-distribution boards.

Efficient Pulse-Operated Switching Control
Latching relays such as the ABB E290 change and retain their contact state in response to electrical control pulses. This means the coil does not need to remain continuously energised after switching, providing an efficient method of remotely controlling electrical loads from pushbuttons or compatible control devices.
The E290 series is particularly suitable for applications where loads such as lighting circuits need to be operated from several locations. Its modular DIN rail construction and robust electromechanical design make it a practical solution for modern building, distribution and electrical 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 electrical control panels.
- Pulse-operated remote switching systems.
