Why Choose the ABB E290-32-11/48 Latching Relay?
The ABB E290-32-11/48 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 and one normally closed contact, providing complementary switching from a compact DIN rail device.
The E290-32-11/48 uses an impulse-operated mechanical latching mechanism. A short electrical control pulse changes the relay state, after which the contacts remain mechanically held in their selected position without continuous coil energisation until another switching impulse is applied.
With a 250 V AC rated operating voltage and 48 V AC / 24 V DC control voltage, this model provides a practical solution for higher-current low-voltage control applications. Its 1NO + 1NC configuration is particularly useful where one circuit must close while another opens when the relay changes state.
Key Advantages
- High 32 A rated current for demanding electrical switching applications.
- 1NO + 1NC contact configuration for complementary switching functions.
- 48 V AC / 24 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.
Key Features

- 32 A rated current.
- 250 V AC rated operating voltage.
- 1NO + 1NC contact configuration.
- 48 V AC / 24 V DC control voltage.
- Impulse-operated mechanical latching mechanism.
- Maintains its contact state without permanent coil power.
- Front manual operating facility and contact-position indication.
- DIN rail mounting with screw-terminal connections.
High-Current Complementary Impulse Switching
ABB E290 latching relays use short electrical control impulses to change their switching state. Once actuated, the internal mechanical mechanism holds the contacts in position without requiring the relay coil to remain continuously energised. A subsequent control impulse changes the switching state again, making the technology well suited to multi-point control applications.
The E290-32-11/48 combines this energy-efficient operating principle with a 32 A switching rating and complementary 1NO + 1NC contacts. When the relay changes state, the normally open contact closes as the normally closed contact opens, enabling coordinated load, control and signalling functions from a single modular device.
Typical Applications
- High-current lighting control circuits.
- Lighting controlled from multiple push-button locations.
- Residential and commercial building installations.
- Public buildings and communal electrical systems.
- Industrial electrical installations.
- Complementary load and signalling circuits.
- Electrical distribution boards and control panels.
- DIN rail mounted impulse-control systems.
