Designed to protect today’s equipment and systems,Littelfuse semiconductor fuses are manufactured withLittelfuse-developed technology that sets tomorrow’s stan-dards for accuracy, consistent quality, reliability, and predict-able performance.By using advanced metallurgical, polymer,and materials research;mathematical modeling, and comput-erized statistical analysis;Littelfuse engineers have redefined“State-of-the-Art.”APPLICATIONSDesigned specifically for supplementary protection of semiconducting devices such as silicon controlled rectifiers(SCR’s), diodes, thyristors, triacs, transistors, and similarsolid-state devices.These devices are used in power equipment including variable speed drives, power rectifiers,UPS systems, DC power supplies, and in a wide range ofelectronic equipment.May be used wherever extremely fast-acting, current-limitingfuses with no time delay are required.SPECIFICATIONSVoltage Ratings:L15S:150 V AC/DC (1 – 60A)150 VAC (70 – 1000A)100 VDC (70 – 1000A)L25S:250 V AC/DC (1 – 200A)250 VAC (225 – 800A)200 VDC (225 – 800A)L50S:500 VAC/450VDCL60S:600 VACKLC:600 VACL70S:700VAC/650VDCInterrupting Rating:AC:200,000 rms amperes (L15S series 100,000 amperes)DC:20,000 amperesAmpere Range:1 – 1000 amperesSee Rating Table for ratings available in each series.Approvals:UL Recognized under the Components Programand CSA Recognized under the ComponentAcceptance Program.UL File No:E71611CSA File No:LR29862L15S and L25S series fuses are LittelfuseCertified for DC ratings shown in Rating Table.AMPERE RATINGSSee Rating Table.RECOMMENDED FUSE BLOCKSLSCR series:Refer to Fuse Block section of this catalog foradditional information.SAFETYs200,000 A.I.R.— Reliable interruption of all overcurrents upto 200,000 amperes ...meets present and future systemrequirements.(Note:L15S series has 100,000 A.I.R.)sExtremely Current Limiting — Low I2t and peak let-throughcurrents meet most semiconductor requirements.sUL Recognized — Littelfuse semiconductor fuses are recognized under the components program of UnderwritersLaboratories, Inc., and carry the mark.UL Recognizedsemiconductor fuses may be used to provide supplemen-tary protection in UL listed equipment.LONGER EQUIPMENT LIFEsLow Watt Losses — Means less heating and power consumption in circuit.sControlled Transient Overvoltages — All circuits are subjectto transient overvoltages during fault current interruption.These transient overvoltages (arc voltages) start when fuselinks melt or circuit breaker contacts part, and subsidewhen circuit is interrupted.Semiconductors are very sensitive to overvoltages.Littelfuse semiconductor fusedesigns keep transient overvoltages to low levels and helpreduce semiconductor failure.元器件交易网www.cecb2b.com
