Features / Benefits

• Provides Motor Overload, Ground Fault and Short-Circuit Protection
• When Used in Circuits Subject to Surge Currents Such as Those Caused by Motors, Transformers and Other Inductive Components, These Fuses Can be Sized Close to Full-Load Amps to Give Maximum Over Current Protection
• The Time-Delay Feature Makes it Possible to Use Fuse Amp Ratings Which are Much Smaller than Those of Non-Time Delay Fuses
• Considerable Cost Saving Occurs by Permitting the Use of Smaller Size Switches, Panels and Fuses Themselves
• Provides a Good Degree of Short-Circuit Protection (Greater Current-Limitation) to Help Protect Downstream Components from High Fault Currents
• Gives Motor Running Back-Up Protection to Motors without Extra Cost
• Helps Protect Motors Against Burnout from Overloads and Single-Phasing When Sized Properly
• Simplifies and Improves Blackout Prevention
• Dual-Element Fuses Can be Applied in Circuits Subject to Temporary Motor Overloads and Surge Currents to Provide Both High-Performance, Short-Circuit and Overload Protection
