Why Choose the ABB E297-16-20/24 Installation Relay?
The ABB E297-16-20/24 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 versatile 24 V AC/DC control coil.
The E297 series uses an electromagnetically operated switching mechanism controlled by a maintained control signal. When the coil is energised, the relay closes its normally open contacts and remains operated while the control voltage is present; when the control voltage is removed, the relay returns to its neutral position. Its optimised coil provides low switching noise and low power loss for dependable operation in electrical distribution boards.
With a 16 A rated current, 250 V AC rated voltage, 24 V AC/DC control voltage and 2NO contact configuration, the E297-16-20/24 is well suited to lighting, ventilation, air-conditioning and similar electrical control circuits. Its compact 18 mm DIN rail format enables straightforward integration into modular distribution boards and control panels.

Reliable Switching for Electrical Installations
Monostable installation relays such as the ABB E297-16-20/24 provide electrically controlled switching for loads that need to remain active while a maintained control signal is applied. Energising the 24 V AC/DC coil closes the two normally open contacts, while removing the control voltage automatically returns the relay to its neutral position.
The E297 series is designed primarily for industrial plants while also being suitable for commercial and public buildings. Its compact DIN rail construction, 16 A switching capability and AC/DC control-coil compatibility make the E297-16-20/24 a practical solution for lighting, air-conditioning, fan and other compatible control applications.
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.
