Why Choose the ABB E297161012 Installation Relay?
The ABB E297161012, type designation E297-16-10/12, 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 one normally open contact in a compact single-module DIN-rail format.
The E297-16-10/12 features one normally open (1NO) main contact and a 12 V AC control coil. As a monostable relay, its contact remains operated while the control voltage is applied to the coil and automatically returns to its normal open position when the control voltage is removed, providing straightforward maintained-control switching.
With a rated operational voltage of 250 V AC, rated current of 16 A and operating frequency of 50/60 Hz, the E297161012 provides reliable load control in an 18 mm-wide DIN-rail module. Its low-loss coil, low switching noise and temporary manual operating lever make it a practical choice for residential, commercial and industrial electrical control systems.

Reliable 12 V AC Monostable Load Control
A monostable installation relay is an electromechanical switching device controlled by a continuous coil signal. When 12 V AC is applied to the ABB E297-16-10/12 control coil, its normally open contact closes and remains operated while the coil is energised; when the control voltage is removed, the contact automatically returns to its normal open position.
ABB's E297 range uses coils designed for low switching noise and low power loss, helping support reliable operation in modular electrical installations. The E297-16-10/12 can also be combined with compatible E298 main contact modules to increase the number of power contacts and E299 auxiliary contact modules for additional signalling and control functions.
Typical Applications
- Residential and commercial lighting control.
