Approvals

• UL listed to standard 248-12 File E2137
• DC listed to UL standard 248
• CSA certified to standard C22.2 No. 248.12


Reducer Fuses

• Reducer fuses are a permanent solution to decrease current rating
• Reduced amp ratings designed to fit into larger fuse holders
• Lower the amp rating of the system without replacing fuse holders or fuse panel
• Ratings available from 110 to 400 Amperes


 Applications



Time delay fuses are the most useful fuses for motor branch circuit application. A time delay fuse can be sized closer to motor full load current, providing a degree of overload protection, better short circuit protection, and possible use of a smaller disconnect switch.

Some example applications include:
• Motors
• Safety Switches
• Transformers
• Branch Circuit Protection
• Disconnects
• Control Panels
• All General-Purpose Circuits
