nVent RAYCHEM CS-150-UNI-PI Connection And Splice Kit


RAYCHEM CS-150-UNI-PI - universal connection and splice kit for series resistance trace heating cables

Series heating cables like RAYCHEM XPI-NH, XPI and XPI-S typically require a section of cold lead cable to connect to a junction box.

The RAYCHEM CS-150-UNI-PI is a universal low profile, cold applied, under insulation connection kit providing a reliable connection from a heating cable to a cold lead (max 4 mm²), two heating cables to a power cable (max 2.5 mm²) or two heating cables (splice).The electrical connection is realized via a terminal block and does not require special tools.

  • Max current: 32A (dependent on configuration)
  • Allows connection to a standard 3-core power cable

Key benefits:

  • Universal kit for a wide range of PI series resistance trace heating cables
  • No hot work permit required, the kit is cold applied
  • No special tools required
  • Small geometry for installation under the insulation
  • Generic approval for use in hazardous areas based on size/diameter, kit can also be used with PI series resistance trace heating cables from other manufacturers
