UL 98, Fused (Fuserbloc Series - Front Operated)

Ferraz Shawmut FUSERBLOC disconnect switches are extremely durable, manually operated, fusible disconnect switches. These switches employ double break contacts per pole that ensure complete isolation of the fuse when the switcdh is in the OFF position. With safety in mind, all FUSERBLOC switches are supplied with fuse covers and line side shrouding as a standard feature. These switches provide the ultimate in short circuit protection when used with Ferraz Shawmut's Class CC, J or L fuses. These heavy duty switches are designed with the most up-to-date fuse and disconnect switch technology available. Designed to meet the UL98 standard, the FUSERBLOC gives you the product that "makes and breaks" power circuits on load. FUSERBLOC switches are tested and approved for use in the most demanding applications, such as "Service Entrance". The optional TEST function (up to 400A) enables testing of the control circuit auxiliaries without switching the main contacts. This function provides a simple alternative to a separately wired push button. A wide array of handles are available to meet OSHA padlocking requirements, NEMA configurations and defeater options.
