As part of the prestigious Low-Peak™ series, this dual-element fuse offers a minimum 10-second time-delay at 500% of the rated current. This allows the fuse to withstand high inrush currents and temporary overloads from motors and transformers, effectively eliminating nuisance tripping while ensuring robust protection during actual fault conditions.\u003c\/p\u003e\n\u003cp\u003eWith a 300kA interrupting rating at 600Vac, the LPJ-450SP provides the highest level of short-circuit protection available. Its current-limiting design significantly reduces the peak let-through current and destructive thermal energy (I²t), safeguarding downstream equipment such as switchgear, motor starters, and power panels. The compact Class J footprint allows for significant space savings in enclosure design compared to Class R or Class K alternatives.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eEaton\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eBussmann series\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCatalog Number:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eLPJ-450SP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Class:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eClass J\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e450 A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e600 Vac, 300 Vdc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupting Rating:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e300kA Vac RMS Sym., 100kA Vdc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTime-Delay:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e10 seconds (minimum) at 500% of rated current\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertifications:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eUL Listed (JDDZ.E4273), CSA Certified (22.2 No. 248.8), CE, RoHS Compliant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnergy Efficient:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eDual-element construction results in lower internal resistance, reducing heat dissipation and operating costs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSimplified Coordination:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eMaintains a consistent 2:1 ampacity ratio for all Low-Peak fuses, making selective coordination easy and reliable.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReliability:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eLong time-delay minimizes downtime caused by transient surges and motor starting currents.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnhanced Safety:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eProvides Type 2 \"No Damage\" protection for NEMA and IEC motor controllers when properly sized.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eApplication:\u003c\/strong\u003e The LPJ-450SP is the industry standard for protecting branch circuits, feeder circuits, and motor control centers.
