Why Choose the ABB E290-16-10/48 Latching Relay?
The ABB E290-16-10/48 is a compact and reliable electromechanical latching relay designed for energy-efficient switching of lighting and other suitable electrical loads from multiple control points. As part of the ABB E290 latching relay series, it combines a 16 A switching rating with one normally open contact and a 48 V AC / 24 V DC control coil.
Unlike a conventional monostable relay, the E290 uses an impulse-operated mechanical latching mechanism. Each brief control pulse changes the contact state, after which the contact remains mechanically latched without continuous coil energisation. This operating principle reduces control-circuit power consumption and makes the relay particularly suitable for lighting circuits controlled from multiple normally open push-buttons.
With a 16 A rated current, 250 V AC rated voltage, 48 V AC / 24 V DC control voltage and 1NO contact configuration, the E290-16-10/48 provides efficient impulse switching for residential, commercial and industrial installations. Its compact 18 mm DIN rail format enables straightforward integration into modular distribution boards and control panels.

Energy-Efficient Impulse Switching for Lighting Control
Latching relays such as the ABB E290-16-10/48 change their contact state each time a short electrical impulse is applied to the control coil. The internal mechanical mechanism then holds the contact securely in its new position without continuous coil energisation until another control impulse changes the state again.
This switching principle is particularly useful where lighting needs to be controlled from multiple locations using normally open push-buttons. The E290-16-10/48 combines a 16 A contact rating with 48 V AC / 24 V DC control compatibility, making it a practical solution for residential, commercial, public-building and industrial electrical installations.
Typical Applications
- Multi-point lighting control systems.
- Staircase and corridor lighting.
