CSA Certified, Class 1422-02, File 53787,
Class J per CSA 22.2 No. 248.
Features:
• Industry's only UL Listed and CSA Certified fuse with a
300kA interrupting rating that allows for simple, worry-free
installation in virtually any application.
• Fast short-circuit protection and dual-element, time-delay
performance provide ultimate protection.
• Reduces existing fuse inventory by up to 33% 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 singlephasing 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.
