Features / Benefits

• Fast Short-Circuit Protection and Dual-Element, Time-Delay Performance Provide Ultimate Protection
• Reduces Existing Fuse Inventory by up to 33 Percent When Upgrading to Low-Peak Fuses
• Consistent 2:1 Ampacity Ratios for All Low-Peak Fuses Make Selective Coordination Easy
• Long Time-Delay Minimizes Needless Fuse Openings Due to Temporary Overloads and Transient Surges
• Current-Limitation Protects Downstream Components Against Damaging Thermal and Magnetic Effects of Short-Circuit Currents
• Dual-Element Fuses have Lower Resistance than Ordinary Fuses So They Run Cooler
• Can Often be Sized for Back-Up Protection Against Motor Burnout from Overload or Single-Phasing If Other Overload Protective Devices Fail
• Proper Sizing Can Provide "No Damage" Type 2 Coordinated Protection for NEMA and IEC Motor Controllers
• Space-Saving Package for Equipment Downsizing
