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
