60 Amp Dual-Element Time-Delay Class J Fuse (600V)

Note: Image displayed may not represent actual product. 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. 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
