Subject: End of Life and New Design Introduction
Cooper Bussmann has redesigned the line of CH Series Modular Fuse Holders for 14x51mm fuses.
As a result, the old design has reached its End of Life and is no longer available effective immediately.
The new design is interchangeable with the old design – see detailed dimensions on next page.
