Catalog Symbol: JFL Quick-Acting Current-Limiting Volts: 600Vac (or less) Amps: 1 to 60A IR: 200kA RMS Sym. Agency Information: CE, UL Listed, Std. 248-8, Class J, Guide JDDZ, File E162363, CSA Certified, HRCI-J C22.2 No. 248.8, Class 1422-02, File 53787 Features • Single-element, current-limiting fuses provide superior short-circuit protection. • Protects low interrupting capacity circuit breakers. Limits the short-circuit current to meet the interrupting capacity requirements of existing equipment. • On older systems available short-circuit current may exceed the interrupting capacity of the circuit breakers, fuses can be installed in series with existing equipment. • Well suited for lighting and heating circuits and other non-inductive loads. • Provides component short-circuit protection in compliance with NEC® 110-10, where protection devices shall clear a fault without “extensive damage” to the circuit components. • High interrupting rating helps meet the requirements of future system expansion and the increases in available utility short-circuit current. •

Catalog Symbol: JDL Dual-Element, Time-Delay – 10 seconds (minimum) at 500% rated current Current-Limiting Volts: 600Vac (or less) Amps: 1 to 60A IR: 200kA RMS Sym. 300kA RMS Sym. (self certified) Agency Information: CE, UL Listed — Class J, Guide JDDZ, File E162363, CSA Certified, HRCI-J 200,000 AIR, Class J per CSA 22.2 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.

Benefits: • True dual-element construction allows sizing of 125% FLA for motor backup protection. • Superior overload and cycling capabilities. • Current limiting provides component short-circuit protection. Applications: • Recommended for AC power distribution system mains, feeders, and branch circuits. • Protection of motors and motor branch circuits. • Protection of transformers and other inductive loads. • All general-purpose applications including lighting
