The CUTLER ARD440SR Control Relay (Cutler-Hammer ARD440SR) uses a 120 V DC coil to energize its switching contacts in industrial control circuits. This DC-coil relay serves as a control device in automation and panel applications, providing isolation between the control logic and the load. With a 120 VDC coil, it is suited for systems that supply 120 V DC control signals and require reliable actuation in control panels.
