ACV Relay holder 45mm 5476v019

ACV Relay holder 45mm 5476v019 is a connector component designed for mounting and interconnecting plug-in relays within burner or boiler control panels. It provides a fixed socket for the relay, ensuring electrical contact and mechanical retention. This holder is compatible with the Prestige 24 Solo boiler model. The 45mm dimension refers to the height or pitch between rows, and it is an OEM part for ACV boilers.

Parts of this type are selected by matching the relay base layout, including pin count, pin diameter, and spacing, as well as the current and voltage rating of the circuit. The holder's terminals are typically designed for quick-connect or screw-clamp wiring. Before ordering, confirm the relay part number and the holder part number together to ensure compatibility. The 45mm dimension should be cross-referenced with the original relay base specification.

A damaged or corroded relay holder can cause intermittent operation or total loss of a function, similar to a poorly mated connector. Signal loss, spurious lockouts, or erratic modulation may trace back to the holder rather than the relay itself. Inspect the holder contacts for signs of overheating and verify that the relay clips firmly into place.
