Agency Information: CE, UL Listed - Special Purpose*, Guide JFHR, File E56412, CSA Certified (200k AIR) Class J per CSA-22.2 No. 248.8, Class 1422-02, File 53787.
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.Features and Benefits
• Separate overload and short-circuit elements provide time delay for sizing of high inrush loads linked with Class J current limitation.
• Selective coordination ratio of 2:1 (within Low-Peak fuse family) prevents electrical shutdowns from extending beyond the failed circuit.
• Series combination ratings with branch circuit breakers allows broad range of coverage, independent of breaker manufacturer.Typical Applications
• Power Panelboards
• Branch Circuit Breaker Panelboard Mains
• Machinery Disconnects
