Why Choose the ABB E297-16-20/8 Installation Relay?
The ABB E297-16-20/8 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 rated switching current with two normally open contacts and an 8 V AC control coil.
This electromagnetically operated relay provides dependable remote switching from a maintained control signal. The E297 series features a low-noise control coil and low thermal power loss, making it well suited to electrical distribution boards and control panels where efficient, reliable operation is required. A front operating lever also permits temporary manual operation and provides an indication of contact position.
With a 16 A rated current, 250 V AC rated contact voltage and 8 V AC coil control voltage, the E297-16-20/8 provides two normally open switching contacts in a compact 18 mm DIN rail module. This makes it suitable for controlling lighting, ventilation, air-conditioning and other electrical loads while conserving valuable panel space.
