Cluster Blocks

Cluster blocks offer manufacturers of air conditioning and refrigeration products a low-cost, fully insulated, quick-connect means of electrically connecting sealed hermetic header pins on compressors. They feature high impact resistance to shock and abuse, and long-life performance in the presence of oils and refrigerants.

 Since the connectors accept pins from only one side, the danger of reversing polarity at the time of installation is minimized. Housings accept both lead wire and AMPLIVAR direct connect pin receptacle terminals. These are precision formed and available on reels for high speed application.
