Fast response to damaging short-circuit currents

• True dual-element fuses with a minimum 10 second time-delay 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 300kA (self-certified)
• High degree of current limitation due to the fast speed-of-response to short-circuits
• Faster response to damaging short-circuit currents than mechanical overcurrent protective devices educes 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-limiting ability cannot be substituted
• Space-saving package for equipment down sizing
• Current-Limiting Volts: 600Vac (or less)
• Current-Limiting IR: 200kA RMS Sym., 300kA RMS Sym. (self-certified)
