Why Choose the ABB E297-16-20/230 Installation Relay?
The ABB E297-16-20/230 is a compact and reliable monostable installation relay designed for switching electrical loads in industrial, commercial and building control applications. As part of the ABB E297 installation relay series, it combines a 16 A switching rating with two normally open contacts and a quiet 230 V AC control coil.
The E297 series uses an electromagnetically operated switching mechanism controlled by the presence of voltage at the relay coil. When the control voltage is applied, the relay operates its contacts and remains energised while that voltage is maintained; when the control voltage is removed, the relay returns to its normal state. Its optimised coil helps minimise power loss and operating temperature while providing quiet switching suitable for electrical distribution boards.
With a 16 A rated current, 250 V AC rated voltage, 230 V AC control voltage and 2NO contact configuration, the E297-16-20/230 is well suited to switching lighting, ventilation, air-conditioning and similar electrical loads. Its compact 18 mm DIN rail format enables straightforward integration into modular control and distribution panels.

Reliable Switching for Electrical Installations
Monostable installation relays such as the ABB E297-16-20/230 provide electrically controlled switching for loads that need to remain active while a control voltage is applied. The electromagnetic coil operates the main contacts when energised and automatically returns them to their normal state when the control voltage is removed.
The E297 series is suitable for industrial installations as well as commercial and public buildings. Its compact DIN rail construction, quiet magnetic system and 16 A switching capability make it a practical solution for controlling lighting, ventilation, air-conditioning and other compatible electrical loads.
Typical Applications
- Lighting control circuits.
- Ventilation and fan switching.
- Air-conditioning control systems.
- Commercial and public building installations.
- Industrial electrical control panels.
- DIN rail distribution boards and automation systems.
