Why Choose the ABB E2971610115 Installation Relay?
The ABB E2971610115, type designation E297-16-10/115, 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 industrial, commercial and public-building control applications.
The E297-16-10/115 features one normally open (1NO) main contact and a dual-rated control coil for 115 V AC or 110 V DC. 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.
With a rated current of 16 A, rated operational voltage of 250 V AC and an AC operating frequency of 50/60 Hz, the E2971610115 provides reliable switching in a compact 18 mm DIN-rail module. Its low-loss coil, temporary manual operating lever and compatibility with additional ABB contact modules make it a flexible solution for modular electrical control systems.

Reliable AC/DC 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 appropriate 115 V AC or 110 V DC control voltage is applied to the ABB E297-16-10/115, the relay operates its normally open contact; when the control voltage is removed, the relay automatically returns to its normal position.
ABB's E297 range uses an optimised control coil with low power loss to support clean, efficient operation within electrical distribution boards. The E297-16-10/115 can also be combined with compatible E298 main contact modules to expand the power-contact arrangement and E299 auxiliary contact modules for additional signalling or control functions.
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.
