Prevent One Monster of a Problem With Our
Amp-Trap® High-Speed J Fuse
Most of today's drives and soft-starters don't have room for the high-speed internal fusing that protects their sensitive power semiconductors. And while traditional branch circuit protection meets NEC® requirements, it leaves motor controllers vulnerable to costly damage and downtime.
That's why Ferraz Shawmut created the Amp-Trap High-Speed J fuse. Specifically designed to safeguard electronic motor controllers, this monster of a fuse combines the overload capacity and dimensions of a Class J with the performance of a semiconductor fuse.

Our Amp-Trap® High-Speed J is the only fuse designed to provide both branch circuit protection and high-speed semiconductor protection for electronic motor controllers. |
The result is one fuse that provides two kinds of protection the branch circuit protection required by the NEC and the high-speed protection you need to prevent damage to your motor controller's sensitive internal electronics.
