Low-Peak™ Upgrade Program

Bussmann provides the easiest and fastest way to select and specify the right fuse. By grouping our low voltage fuses into three tiers of protection, and four fuse families within those tiers, we've sped up specification and selection and made replacement easy. Leveraging our ultimate protection fuses, the Bussmann Low-Peak™ Upgrade program couples the industry's most advanced circuit protection with our extensive technical knowledge to deliver enhanced safety, improved system reliability and simplified inventory.

With just three simple steps, it's easier than ever to improve your circuit protection while efficiently reducing your fuse inventory SKUs and cost. What's more, you'll save time and increase productivity - all by using Bussmann Low-Peak fuses.
