The ABB CR-U120AC3 is a reliable pluggable universal interface relay designed for industrial automation, control panels and electrical switching applications. As part of the advanced ABB CR-U relay series, it provides dependable signal isolation, circuit control and flexible switching performance for PLC interfaces, machinery and industrial systems.
This universal relay features a robust plug-in construction with durable circular pin terminals engineered for repetitive industrial use. The modular design allows the relay to be combined with compatible ABB CR-U sockets and mounted easily on DIN rails, providing a flexible and service-friendly solution for modern electrical control cabinets.
With a 120 V AC rated control supply voltage, 3 changeover (SPDT) contacts and contact ratings of 250 V AC / 10 A, the ABB CR-U120AC3 enables multiple circuits to be switched from a single control signal. The relay includes a test button for manual actuation and commissioning support.
Interface relays such as the ABB CR-U120AC3 provide electrical isolation between automation controllers and connected equipment. They allow low-power control signals from PLCs and industrial controllers to safely operate higher-load circuits while improving system flexibility and reliability.
The ABB CR-U relay family is designed for industrial applications requiring dependable switching, modular installation and easy maintenance. The CR-U120AC3 offers a practical solution for engineers requiring reliable control interfaces in automation systems.
