ACV Contactor 54762064

The ACV Contactor 54762064 is a genuine ACV control system component, also referenced as a power relay. It is categorized under plugs and connectors and is designed to carry low-voltage signals and mains supply between the control board and components. This item is installed on ACV Smart E Plus, Prestige Box Mono 100, and HeatMaster 71 models. Its primary function is to control power supply to heating elements and pumps, ensuring smooth switching and overload protection. No further technical specifications are provided for this specific item.

Parts of this type are selected by pin count, pitch, and keying rather than by function. When replacing a component from this category, verify the part's actual role—whether it functions as a switching contactor or as a connector—against the original. For contactors, ensure the coil voltage and contact rating match the original; these details must be obtained from the appliance documentation or the existing part. Inspect mating surfaces for damage and confirm the locking mechanism engages fully.

Poor contact in a connector can reproduce almost any electrical fault symptom, making connectors a routine suspect during fault finding. For contactors, loose or corroded terminals can mimic control failures. If the control system fails, check the electrical connections and the condition of the contactor or connector.
