TE Raychem CBR breakouts are medium wall heat shrink cable breakouts for low voltage power cables up to 1 kV. They insulate and protect the cable crutch on low voltage accessories, and seal against moisture and mechanical stress in low voltage splices, especially transition joints.
Dimensions are in inches, with mm in parentheses.
