Why Choose the ABB E290-32-10/115 Latching Relay?
The ABB E290-32-10/115 is a high-current electromechanical latching relay designed for impulse-controlled switching in lighting, building control and electrical distribution applications. Part of the ABB E290 range, it combines a 32 A rated current with one normally open contact, providing reliable load switching from a compact DIN rail device.
The E290-32-10/115 uses an impulse-operated mechanical latching mechanism. A short electrical control pulse changes the relay state, after which the contact remains mechanically held in its selected position without continuous coil energisation until another switching impulse is applied.
With a 250 V AC rated operating voltage and 115 V AC / 60 V DC control voltage, this model is suited to higher-current impulse-control installations. Its compact 18 mm modular format makes it particularly useful in distribution boards where reliable switching performance and efficient use of DIN rail space are required.
Key Advantages
- High 32 A rated current for demanding electrical switching applications.
- Single normally open (1NO) contact for straightforward load switching.

High-Current Impulse Switching with Mechanical Latching
ABB E290 latching relays use short electrical control impulses to change their switching state. Once actuated, the internal mechanical mechanism holds the contact in position without requiring the relay coil to remain continuously energised. A subsequent control impulse changes the switching state again.
This operating principle makes the E290-32-10/115 particularly suitable for higher-current lighting and building-control circuits operated from multiple push-button locations. The 1NO contact provides straightforward load switching, while the 32 A rating extends the relay's suitability to applications requiring greater switching capacity than standard 16 A impulse relays.

- Lighting controlled from multiple push-button locations.
- Residential and commercial building installations.
- Public buildings and communal lighting systems.
