In the Sentron Busway line, 3 single-phase service heads and3-phase service head connections are available. The standard service entrance connection is the 3-phase service head whichconsists of one service head for all three phases. 3 single-phase service heads consist of three heads – one for each phase andmay be used to meet the requirements of certain applications. To ensure ease of installation of incoming cables, both types ofSentron service heads are constructed so that the lugs face the Glastic bottom of the box. The Glastic bottom providesinsulation and protection to the incoming cables.Three Single-Phase Service HeadsSuffix V1TX14 BUSWAYSYSTEMSThree-Phase Service Heads, Dimensions (standard/min.)Cable Lugs perDimensions Inches (mm) Phase and Neutral GroundAmpere Rating Three-Phase “B” Qty.
