Features:

• Industry’s only UL Listed and CSA Certified fuse with a 300kA Vac interrupting rating that exceeds requirements for virtually all applications

• Long time-delay minimizes needless fuse openings due to temporary overloads and transient surges

• Easy selective coordination with all Low-Peak fuses using simple 2:1 ampacity ratio

• Can often be sized for back-up protection against motor burnout from overload or single-phasing if other overload protective devices fail

• 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

• 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

• Space-saving package for equipment downsizing
