Potter-Brumfield KB-23AG-120 Relay 120V AC Coil

Potter-Brumfield KB-23AG-120 is an electromechanical relay with a 120V AC coil. The KB-23AG-120 designation identifies this exact model in Potter-Brumfield’s KB-23 family, indicating a 120-volt alternating-current coil used to energize its switching contacts. As a relay, it acts as an electrical switch controlled by a low-power signal, enabling the routing of current in a separate load circuit when the 120V AC coil is energized. The 120V AC coil rating specifies the voltage required on the control side to operate the device, compatible with control systems that supply a 120V AC control voltage. Energizing the coil converts electrical energy into magnetic force that moves the contacts to complete or break a circuit. In practice, this type of relay provides a means to control a higher-power load from a lower-power control signal while maintaining electrical isolation between the control circuitry and the switched load. The KB-23AG-120 variant provides the specific coil rating you need when sourcing a replacement or a part for a compatible system that requires a 120V AC coil relay from the Potter-Brumfield KB-23 line.
