Why Choose the ABB E294/230 Central On-Off Switching Module?
The ABB E294/230 is a compact central on-off switching module designed for centralised control of compatible ABB E290 latching relay installations. Operating with a 230 V AC control voltage, it provides a practical way to add central switching commands to impulse-controlled lighting and electrical control systems.
As an accessory for ABB E290 latching relays, the E294/230 enables individual relay-controlled circuits to be incorporated into a centralised control arrangement. This is particularly useful in installations where multiple lighting circuits need to retain their normal local push-button control while also allowing a central command to switch the associated relays on or off.
With a 1 A rated current, 250 V AC rated voltage, 230 V AC control circuit voltage and compact 18 mm DIN rail format, the E294/230 is suited to residential, commercial, public-building and industrial control systems using compatible ABB E290 devices.

Centralised Control for ABB E290 Latching Relay Systems
The ABB E294/230 extends compatible E290 latching relay installations with a centralised on-off control function. This allows multiple relay-controlled circuits to form part of a coordinated control system while the E290 devices continue to provide energy-efficient impulse switching and mechanical retention of their switching state.
Centralised switching can be particularly useful in buildings with numerous independently controlled lighting circuits, where a central command is required in addition to local controls. Its modular DIN rail construction allows the E294/230 to be incorporated alongside compatible ABB control devices in distribution boards and electrical control panels.
Typical Applications
- Central on-off control of compatible ABB E290 latching relays.
- Centralised lighting control systems.
- Residential building control installations.
- Commercial and public building lighting systems.
- Factory and industrial electrical installations.
- DIN rail distribution boards and control panels.
