De Dietrich 81997721 sac de connecteurs DB115

The De Dietrich 81997721 is a bag of connectors, listed under catalogue article 336.388.001 and identified by the manufacturer codes 81997721 and 336.388.001. This item belongs to the category of plugs and connectors. Parts of this type carry low-voltage signals and mains supply between the control board and the various components of a burner or boiler system. They are selected by connector series, pin count, pitch, and keying rather than by the specific function they perform. When replacing such connectors, the heating engineer must match these mechanical characteristics exactly. Poor contact in a connector can reproduce almost any electrical fault symptom, making connectors a routine suspect during fault finding. It is important to verify that the conductor cross-section, insulation temperature class, length, and terminal type are appropriate for the application. No further technical details about this specific bag of connectors are available from the provided data; the part number and brand are as stated.
