As a cornerstone of the Low-Peak™ family, this dual-element, current-limiting fuse provides a minimum 10-second time-delay at 500% of the rated current. This allows the system to accommodate harmless transient surges and motor intensive starting currents, significantly reducing downtime and service costs associated with nuisance tripping.\u003c\/p\u003e\n\u003cp\u003eThe LPJ-400SP is engineered with a massive 300kA interrupting rating at 600Vac, offering the highest level of safety for industrial power systems. Its advanced current-limiting performance restricts the magnitude of short-circuit currents, protecting downstream components from the damaging thermal and magnetic effects of faults. Its space-saving Class J design is ideal for modern, compact equipment where panel space is at a premium.\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-400SP\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\u003e400 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\u003eStandard Compliance:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eUL Listed Class J, CSA Certified, CE, RoHS Compliant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eKey Performance Advantages:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnhanced Component Protection:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eHigh-speed response to major faults reduces let-through energy to safeguard electrical distribution gear.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEfficient Operation:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eDual-element architecture ensures lower internal resistance, resulting in cooler operation and lower energy consumption in the panel.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelective Coordination:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eSimplifies system design with a consistent 2:1 ampacity ratio required for efficient selective coordination.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVersatile Design:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eOffers Type 2 \"No Damage\" protection for NEMA and IEC motor controllers when sized appropriately.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eApplication:\u003c\/strong\u003e The LPJ-400SP is widely utilized in industrial motor control centers, branch circuit protection, and service entrance equipment.
