Edison(R) JDL Class J 600 Volt, 70 to 600A Dual-Element, Time-Delay Fuses Dimensions (inches) Catalog Symbol: JDL Dual-Element, Time-Delay - 10 seconds (minimum) at 500% rated current Current-Limiting Volts: 600Vac (or less) Amps: 70 to 600A IR: 200kA RMS Sym 300kA RMS Sym. (self certified) Agency Information: CE, UL. Listed - Class J, Guide JDDZ, File E162363, CSA Certified, HRCI-J Class J per CSA C22.2 No. 248.8, Class 1422-02, File 53787 Features * 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. * 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. * 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.
