Fuses Made Simple™

The easiest and fastest way to select and specify fuses

Three Tiers

Three tiers of protection offer distinct levels of performance benefits to help you speed up specification and selection.

Ultimate Protection – The best worry free protection in virtually any application. Unique dual-element construction delivers a powerful combination of all performance options in one fuse - fast short-circuit protection, current limitation, and time-delay performance with up to 300kA interrupting ratings.

Advanced Protection – Application specific protection for sensitive devices and critical components or motors and transformers. Choose between fast short-circuit, current limiting performance or energy efficient, current limiting, time-delay performance based on the application. Featuring 200kA interrupting ratings.

Basic Protection – Basic single-element protection for service, feeder and branch circuit applications. Featuring up to 100kA interrupting ratings.

Four Families - Each with Unique Color-Coded Labels

Inside these three protection tiers are four distinct families - Low-Peak, FUSETRON, Limitron and General Purpose - each represented by a unique color for their key protection and performance benefits.
