Bussmann's UL Class J fuse products extend both our Low-Peak family of products with our LPJ_SP and LPJ_SPI dual-element, time-delay fuses as well as our Limitron line offering fast-acting JKS fuses. The LPJ fuses provide industry leading 300,000 amp interrupting rating at 600Vac RMS Sym and 100kA Vdc while delivering a minimum of 10 seconds of 500% rated current ride-through performance which is ideal for sizing of high inrush loads. The LPJ products are available with optional permanent replace fuse indication. These UL Class J products in sizes 1 to 600 amps provide exceptional performance at 600 VAC and 300 VDC.

Features & Benefits

• Industry only UL Listed and CSA Certified Fuse with a 300 Kiloamp Interrupting Rating that Allows for Simple, Worry-Free Installation in Virtually any Application
• Fast Short-Circuit Protection and Dual-Element, Time-Delay Performance Provide Ultimate Protection
• Reduces Existing Fuse Inventory by up to 33% When Upgrading to Low-Peak Fuses
• Consistent 2:1 Capacity Ratios for All Low-Peak Fuses Make Selective Coordination Easy
• Long Time-Delay Minimizes Needless Fuse Openings Due to Temporary Overloads and Transient Surges
• Current Limitation Protects Downstream Components Against Damaging Thermal and Magnetic Effects of Short-Circuit Currents
• Dual-Element Fuses have Lower Resistance than Ordinary Fuses So they Run Cooler
• They can Often be Sized for Back-Up Protection Against Motor Burnout from Overload or 1-Phase if Other Overload Protective Devices Fail
• Proper Sizing can Provide No Damage Type 2 Coordinated Protection for NEMA and IEC Motor Controllers
• Space Saving Package for Equipment Downsizing
• RoHS Compliant
