Slofast Cutout Fuse Link with 23" Pigtail, 4.2A (Standard Pack 10)

Hi-Line Part-Number: CHM4D2SF23

Transformer Protection
Secondary temporary faults that can be withstood by a transformer will not rupture a SloFast fuse link. If secondary faults persist and become dangerous, the SloFast link will operate, preventing damage to the transformer.

System Protection
When a heavy fault occurs within the transformer primary bushings, a SloFast link clears the transformer from the system before damage can occur, and before any other protective device can operate and cause an unnecessary interruption to any other segment of the system.
