Bussmann LOW-PEAK LPJ SPI Dual-Element Time-Delay Fuses 6-60 Amps Class J 600 Volt General Information: Dimensional Data Permanent fuse Indication. 2.25 ( 0.03) True dual-element fuses with a minimum 10 second time- .81 delay at 500% overload5 ( 0.03) Long time-delay minimizes needless fuse openings due to temporary overloads and transient surges. 1A to 30A Can often be sized for back-up protection against motor 2.38 burnout from overload or single-phasing if other overload ( 0.03) protective devices fail63 High interrupting rating to safely interrupt overcurrents up to 300,000A. 1.06 35A to 60A High degree of current limitation due to the fast speed-of- ( 0.03) response to short-circuits. Faster response to damaging short-circuit currents than Catalog Symbol: LPJ SPI mechanical overcurrent protective devices. Dual-Element, Time-Delay 10 seconds (minimum) at 500% Reduces let-through thermal and magnetic forces in order rated current to protect low withstand rated components. Current-Limiting Proper sizing provides no damage Type 2 coordinated Ampere Rating: 6 to 60A protection for NEMA and IEC motor control in accordance Voltage Rating: 600Vac (or less) with IEC Standard 947-4-1. 300Vdc (or less): 35-60A Dual-element fuses have lower resistance than ordinary fuses so they run cooler. Interrupting Rating: 300,000A RMS Sym. (UL) Lower watts loss reduces power consumption. 100,000A dc Unique dimensions assure that another class of fuse with Agency Information: a lesser voltage rating, interrupting rating or current-Iimiting UL Listed Special Purpose*, Guide JFHR, File E56412 ability cannot be substituted. CSA Certified, 200,000 AIR, Class J per CSA 22.2 No. 248.8 Space-saving package for equipment down sizing.
