Why Choose the ABB E297-16-11/12 Installation Relay?
The ABB E297-16-11/12 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 one normally open and one normally closed contact and a 12 V AC control coil.
The E297 series uses an electromagnetically operated switching mechanism controlled by a maintained control signal. When the coil is energised, the relay changes the state of its contacts and remains operated while the control voltage is present; when the control voltage is removed, the relay automatically returns to its normal state. Its optimised coil provides low power loss and reduced operating temperature for dependable use in electrical distribution boards.
With a 16 A rated current, 250 V AC rated operational voltage, 12 V AC control voltage and 1NO+1NC contact configuration, the E297-16-11/12 provides flexible switching for 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.
