Edison JDL Class J fuses are among the most current limiting time delay fuses available. Their small physical size and high performance characteristics makes Class J fuses ideal for any space-limited application.

Edison Time Delay Fuse, Series: JDL, 250 A, 600 VAC, 200 kA Interrupt, Class: J, Dual Element, 2.11 in Dia x 7.13 in L Body Size

• True dual-element fuses with a minimum 10 s 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 overcurrent's up to 300 kA (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
• 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-limiting ability cannot be substituted
• Space-saving package for equipment down sizing
• Use to protect lower interrupting rating circuit breakers, type 2 no damage protection of IEC style motor starters and contactors
