Why Choose the ABB E2971610230 Installation Relay?
The ABB E2971610230, type designation E297-16-10/230, is a compact monostable installation relay designed for dependable switching of lighting, ventilation, air-conditioning and other electrical loads. Part of ABB's E297 installation relay range, it combines a 16 A contact rating with a compact single-module DIN-rail format for residential, commercial, public-building and industrial control applications.
The E297-16-10/230 features one normally open (1NO) contact and a 230 V AC control coil. The relay remains energised while control voltage is applied to the coil and automatically returns to its normal state when the control voltage is removed, providing straightforward maintained-control operation for a wide variety of electrical loads.
With a rated current of 16 A, rated operational voltage of 250 V AC and operating frequency of 50/60 Hz, the E2971610230 provides reliable switching in a compact 18 mm DIN-rail module. Its optimised low-noise coil, low power loss and manual operating lever make it a practical solution for modular electrical distribution and automation systems.

Reliable Monostable Load Control
A monostable installation relay is an electromechanical switching device whose contact state is controlled by the presence of voltage at its coil. When the 230 V AC control voltage is applied to the ABB E297-16-10/230, the relay operates its normally open contact; when the control voltage is removed, the relay returns automatically to its normal position.
ABB's E297 range is optimised for low switching noise and low coil power loss, helping reduce heat generation within electrical distribution boards. The E297-16-10/230 can also be combined with compatible E298 main contact modules and E299 auxiliary contact modules, providing additional flexibility for more complex switching and signalling arrangements.
Typical Applications
- Residential and commercial lighting control.
- Industrial lighting systems.
- Ventilation and fan control.
- Air-conditioning control circuits.
- Building automation and electrical distribution boards.
- Public-building switching systems.
- Industrial machinery and general load-control applications.
