Edison's UL Class J fuse products are offered in both Dual-Element Time-Delay (JDL) and Fast-Acting (JFL) types. Both types have 200,000 amp interrupting rating at 600Vac RMS Sym amps. Their small physical size and high performance characteristics makes Class J fuses ideal for any space-limited applications. Edison's JFL fuses are best suited for the protection of non-inductive loads such as resistive heating and lighting circuits.

• True dual element fuses with a minimum 10 sec 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 interrupt rating to safely interrupt over currents up to 300 kA
• High deg of current limitation due to the fast speed of response to short circuits
• Faster response to damaging short circuit currents than mechanical over current protective devices
• Reduces let through thermal and magnetic forces in order to protect low withstand rated components
• Dual element fuses have lower resistance than ordinary fuses, hence they run cooler
• Lower watts loss reduces power consumption
• Unique dimensions assure that another class of fuse with a lesser voltage rating, interrupt rating or current limiting ability cannot be substituted
• Space saving package for equipment down sizing
• Proper sizing provides No Damage type 2 coordinated protection for NEMA and IEC motor control in accordance with IEC standard 947-4-1
• Can often be sized for back-up protection against motor burnout from overload or single phasing if other overload protective devices fail
