Spec sheet & sizing guide.

Bayonet fuses protect the transformer from harmful currents as well as protecting the system from failed transformers. A bayonet fuse works well in a two-fuse protection plan with a backup fuse that limits current. The bayonet fuse clears secondary faults and overload currents. While the current-limiting fuse clears high level faults. The two fuses are connected in a series.

If the bayonet fuse is not used in series with a current-limiting fuse, an isolation link is required.


No special tools are required for installation. A utility hot stick is used to remove the bayonet fuse cartridge holder from the transformer. The fuse cartridge is then replaced, and the holder reinserted using a the same hot stick. 

What's the difference between dual sensing, and current sensing?

Current sensing bayonets operate only when exposed to overcurrents. While dual sensing fuses are also designed to operate under high heat.

** Fuse is an integral element/cartridge/end plug design.

Reviews from our customers:

“I spoke with Josh Long and he was the most knowledgeable sales rep on transformers I had the pleasure of speaking with during my 2 month long ordeal to find a very specific transformer for my machine from overseas. I really appreciate his expertise on the matter and I look forward to working Josh again.”

Hien Tran

“I love this company. I'm an electrical contractor and I use them for all my transformer needs and recommend them wherever I can. Josh Long and Chris Stouffer always return my calls and answer my emails. They provide a great, personalized service. It's nice to go straight to the source to buy rather than going through an electrical supply house or another middle man.”

Naomi Doire

“Your service and response was impeccable. The equipment quality is excellent. It was a pleasure to work with Jeremiah. He was fantastic, sent me all the drawings and paperwork superfast. Can't wait to need another transformer. Thank you very much.”
