Why Choose the ABB E290-32-20/230 Latching Relay?
The ABB E290-32-20/230 is a high-current electromechanical latching relay designed for energy-efficient impulse switching of lighting and other compatible electrical loads. As part of the ABB E290 latching relay series, it combines a 32 A rated current with two normally open contacts and a 230 V AC / 110 V DC control coil.
The E290 uses an impulse-operated mechanical latching mechanism. Each control impulse changes the contact state, after which the contacts remain mechanically latched without continuous coil energisation until another impulse is received. A front operating lever also enables 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 2NO contact configuration, the E290-32-20/230 provides two normally open switching paths for demanding residential, commercial and industrial installations. Its compact 18 mm DIN rail format enables efficient use of space in modular distribution boards and control panels.

Energy-Efficient High-Current Impulse Switching
Latching relays such as the ABB E290-32-20/230 change their contact state each time an electrical impulse is applied to the control coil. The internal mechanical mechanism then holds the contacts securely in their new position without continuous coil energisation until another control impulse changes the state.
This switching principle is particularly useful for lighting and other compatible circuits requiring control from one or more normally open push-buttons. The E290-32-20/230 combines two normally open contacts, a high 32 A rating and 230 V AC / 110 V DC control capability, providing flexible impulse switching for residential, commercial and industrial electrical installations.
Typical Applications
- Multi-point lighting control systems.
- Higher-current lighting circuits.
- Staircase and corridor lighting control.
- Commercial and public building electrical systems.
- Factory and industrial lighting installations.
- DIN rail distribution boards and control panels.
