General Information
 
 

• True dual-element fuses with a minimum 10 second timedelay at 500% overload.
• Long time-delay minimizes needless fuse openings due to temporary overloads and transient surges.
• Can often be sized for back-up protection against motor burnout from overload or single-phasing if other overload protective devices fail.
• High interrupting rating to safely interrupt overcurrents up to 300,000A.
• High degree of current limitation due to the fast speed-ofresponse to short-circuits.
• Faster response to damaging short-circuit currents than mechanical overcurrent protective devices.
• Reduces let-through thermal and magnetic forces in order to protect low withstand rated components.
• Proper sizing provides “no damage” Type “2” coordinated protection for NEMA and IEC motor control in accordance with IEC Standard 947-4-1.
• Dual-element fuses have lower resistance than ordinary fuses so they run cooler.
• Lower watts loss reduces power consumption.
• Unique dimensions assure that another class of fuse with a lesser voltage rating, interrupting rating or current-Iimiting ability cannot be substituted.
• Space-saving package for equipment down sizing.
