Why Choose the ABB E290-32-10/48 Latch Relay?
The ABB E290-32-10/48 is a compact and reliable electromechanical latching relay designed for switching electrical loads from one or more control points in building and electrical installation systems. As part of the ABB E290 latching relay series, it combines a high 32 A rated current with pulse-operated switching and a space-saving DIN rail format.
The relay changes the state of its contact each time a control pulse is applied to the coil, allowing loads to be controlled efficiently without continuous coil energisation. A front-mounted manual operating lever provides convenient local actuation and indicates the switching state, making the E290 series well suited to lighting control and distribution applications.
With a 32 A rated current, 1NO contact configuration and 48 V AC / 24 V DC coil control voltage, the E290-32-10/48 provides dependable switching in electrical distribution systems. Its compact 18 mm width allows direct 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 their switching state in response to control pulses from normally open pushbuttons. This operating principle makes it possible to control a load from multiple locations while avoiding the need to keep the relay coil continuously energised.
The E290 series is designed for direct installation in electrical distribution systems and is particularly suitable for lighting control circuits. Its modular DIN rail construction, manual operating lever and range of AC/DC coil voltages provide a practical solution for modern building and electrical control installations.
Typical Applications
- Lighting control from multiple pushbutton locations.
- Main and sub-distribution boards.
- Commercial and industrial building installations.
- Electrical control and switching circuits.
- DIN rail mounted automation and control panels.
- Energy-efficient pulse-operated load control.
