Potter-Brumfield KH-5404 Relay

The Potter-Brumfield KH-5404 Relay is a 24V DC coil electrical relay from Potter & Brumfield (AMF Potter & Brumfield). It is a coil‑energized device designed to switch a separate circuit, providing electrical isolation between a control signal and the load it drives. The KH-5404 designation identifies this unit as part of Potter-Brumfield’s KH family of relays, used in industrial control applications where reliable switching is required. This 24VDC coil version is suitable for control panels, automation cabinets, and other equipment that utilize low‑voltage control logic to operate higher‑voltage or higher‑current circuits. For technicians replacing worn or failed units in legacy systems that call for a 24‑volt coil, KH-5404 offers an established path to restore proper control functionality without forcing changes to surrounding interfaces or wiring schemes.
