Why Choose the ABB E290-32-10/230 Latching Relay?
The ABB E290-32-10/230 is a compact and powerful electromechanical latching relay designed for energy-efficient switching of lighting and other compatible electrical loads. As part of the ABB E290 latching relay series, it combines a high 32 A rated current with one normally open contact and a 230 V AC / 110 V DC control coil.
The E290 uses an impulse-operated mechanical latching mechanism. Each control impulse briefly energises the coil and changes the contact state, after which the contact remains mechanically latched without continuous coil energisation until the next impulse is received. A front operating lever also permits manual operation and provides a visible indication of the contact state.
With a 32 A rated current, 250 V AC rated voltage, 230 V AC / 110 V DC control voltage and 1NO contact configuration, the E290-32-10/230 provides high-current impulse switching in a compact modular device. Its 18 mm DIN rail format enables straightforward integration into residential, commercial, public-building and industrial distribution systems.

Energy-Efficient High-Current Impulse Switching
Latching relays such as the ABB E290-32-10/230 change their contact state each time an electrical impulse is applied to the control coil. The coil is energised only briefly, while the internal mechanical mechanism holds the contact securely in its new position until the next control impulse is received.
This switching principle is particularly useful for lighting and other compatible circuits controlled from multiple locations using normally open push-buttons. The E290-32-10/230 combines a high 32 A contact rating with 230 V AC / 110 V DC control capability, providing energy-efficient impulse switching for residential, commercial and industrial electrical installations.
Typical Applications
- Multi-point lighting control systems.
- Higher-current lighting circuits.
- Staircase and corridor lighting.
- Commercial and public building electrical systems.
- Factory and industrial lighting installations.
- DIN rail distribution boards and control panels.
