LPJ-30SPI

Bussmann® LOW-PEAK ® LPJ_SPI 6-60 Amps General Information: • Permanent fuse Indication. • True dual-element fuses with a minimum 10 second timedelay 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 300,000A. • High degree of current limitation due to the fast speed-ofresponse 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-Iimiting ability cannot be substituted. • Space-saving package for equipment down sizing.
