Why Choose the ABB E290-32-20/48 Latch Relay?
The ABB E290-32-20/48 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 loads to be controlled from one or more pushbutton locations without continuous coil energisation. This operating principle makes the E290 series particularly suitable for lighting control, distribution boards and other applications requiring efficient remote switching.
With a 32 A rated current, 2NO contact configuration and 48 V AC / 24 V DC coil control voltage, the E290-32-20/48 provides dependable switching for electrical distribution and control systems. Its compact modular construction enables straightforward installation on standard 35 mm DIN rails.
Key Advantages
- Compact electromechanical latching relay for pulse-operated switching.
- 32 A rated current for demanding electrical load-control applications.

Efficient Pulse-Operated Switching Control
Latching relays such as the ABB E290 use electrical control pulses to change and retain their contact state. Because the relay does not require its control coil to remain continuously energised to maintain the selected switching position, it provides an efficient solution for remotely controlling electrical loads.
The E290 series is particularly useful where a load must be controlled from several pushbutton locations. Its modular construction and DIN rail mounting make it well suited to main and sub-distribution boards, lighting systems and other 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 electrical control panels.
- Pulse-operated remote switching systems.
