Fuse cutouts provide overcurrent protection and a visible break point for distribution transformers and feeder taps. Silverstone polymer cutouts combine a silicone-rubber housing with a loadbreak-rated fuse tube, cutting weight and improving pollution performance versus porcelain — with complete accessories for hook-stick operation.

Frequently Asked Questions
What fuse link ratings are available?
Fuse links from 1A to 200A in standard K and T speed ratios are available; specify your transformer size and coordination requirements.
Loadbreak vs. non-loadbreak — which do I need?
Loadbreak cutouts allow switching energized load current with the proper tool; non-loadbreak types must only be opened after the circuit is de-energized or unloaded. We supply both.
Can you match our national utility specification?
Yes. Send the utility spec sheet and we will confirm compliance or propose the closest equivalent with deviations listed.
