(UL) Agency Approval: UL Listed — Special Purpose*, Guide JFHR, File E56412 CSA Certified, 200,000 AIR, Class J per CSA 22.2 No. 248.8 Class 1422-02, File 53787 † 0-600A is rated 300 VDC and 20 KAIC. *Meets all performance requirements of UL Standard 248-8 for Class J fuses. Catalog Symbol and Ampere Ratings 1-60 Amps 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 300,000 amperes. • 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.
