Why Choose the ABB E290-32-10/24 Latching Relay?
The ABB E290-32-10/24 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 E290-32-10/24 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 24 V AC / 12 V DC control voltage, this model is well suited to higher-current applications operated from low-voltage control circuits. 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.
- 24 V AC / 12 V DC control voltage for compatible low-voltage control circuits.
- Mechanical latching retains the switching state without continuous coil energisation.
- Front operating lever provides manual operation and contact-position indication.
- Compact 18 mm DIN rail format for space-efficient panel installation.

High-Current Impulse Switching with Low-Voltage Control
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, providing an efficient solution for circuits operated from multiple control points.
The E290-32-10/24 combines this energy-efficient operating principle with a 32 A switching rating and 24 V AC / 12 V DC control. The combination makes it particularly useful where a low-voltage push-button or automation circuit needs to control a higher-current electrical load from a compact DIN rail relay.

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