Bussmann LPJ-175SP Low-Peak Fuse, 175 A, Class J, Dual, Time Delay, 100 kAIC Vdc, 600 V

Description

Features

• Engineered with advanced Low-PeakTM dual-element technology, this fuse securely holds 500% of its rated current for a minimum of 10 seconds to safely accommodate harmless inrush currents. This critical feature eliminates expensive, frustrating nuisance tripping during heavy machinery or transformer startups, ensuring your industrial facility maintains maximum uptime and operational efficiency.
• Boasting an industry-leading 300,000 Amp short-circuit interrupting rating (IR) at 600V AC, this highly efficient fuse actively restricts peak let-through currents during severe fault events. By isolating destructive electrical spikes before they can cause thermal or magnetic damage, it provides superior arc-flash mitigation to safeguard sensitive motor controllers, VFDs, and facility personnel.
• Designed with standard Class J dimensions, this bolted-blade cartridge fuse effortlessly mounts into compatible clip-and-bolt Class J fuse blocks. Its highly compact form factor requires significantly less mounting real estate than traditional Class RK1 or RK5 fuses, allowing panel builders and commercial electricians to design smaller, more cost-effective electrical enclosures without sacrificing overcurrent protection.
• Strictly rated for 175 amps and 600 volts AC (300V DC), this Bussmann series fuse is precisely engineered for demanding industrial mains, feeders, and heavy-duty branch circuits. Fully UL Listed and CSA Certified, integrating this compliant component ensures your commercial electrical distribution network easily passes strict local NEC safety inspections while keeping your facility's operational insurance valid.
