Description

LOW-PEAK CLASS J T/D

Features

  • Engineered with an advanced 10-second time-delay at 500% of its 40-amp rating, this Bussmann Low-Peak fuse effortlessly handles heavy, harmless inrush currents without opening. This critical feature actively eliminates costly manufacturing downtime and frustrating nuisance blowing, ensuring commercial HVAC systems, transformers, and industrial motors start reliably while still offering ironclad overcurrent protection.
  • Boasting an industry-leading 300,000 Amp Short Circuit Current Rating (SCCR) at 600V AC, this highly current-limiting Class J fuse stops catastrophic electrical faults in fractions of a second. By drastically minimizing thermal and magnetic energy let-through, it actively shields downstream equipment like sensitive motor controllers and switchgear from destructive arc flashes and permanent thermal damage.
  • Manufactured strictly to standard Class J dimensions, this compact 40A cartridge fuse requires up to 50% less mounting space than standard Class R equivalents. This space-efficient footprint allows panel builders to significantly downsize electrical enclosures and disconnect switches, saving valuable real estate and reducing material costs without compromising on heavy-duty performance.
  • Fully UL Listed (Guide JDDZ, File E4273) and CSA Certified, this premium protective device guarantees IEC and NEMA Type 2 coordinated protection for motor starters. Relying on this elite safety standard ensures that your expensive contactors and overload relays remain completely undamaged and operational after a severe fault event, drastically reducing component replacement costs and keeping your facility strictly code-compliant.
