Description

Engineered for robust performance in demanding industrial environments, this current-limiting time-delay fuse is an essential component for large distribution switchboards and power panelboards. With an impressive amperage rating of 800A and an interrupt rating of 300 kAIC at 600 Vac, this Class L fuse ensures reliable protection against overloads and short circuits while maintaining safe operation across a wide voltage range of 600 Vac and 300 Vdc. Featuring a bolted blade end connection, its design includes a four-second response time at 500% load, providing timely intervention during fault conditions. Compliant with CE standards, this fuse exemplifies durability and reliability, making it a crucial choice for heavy machinery disconnects and other critical electrical applications. With dimensions of 2.53 inches in height and 2.53 inches in width, it is compact yet powerful, embodying quality engineering that aligns with the stringent demands of contemporary power distribution systems.

Features

  • Engineered with a robust 800-amp capacity and a 600Vac rating, this Class L fuse provides heavy-duty overcurrent protection for large service entrances, main switches, and feeder circuits. Its massive 300 kA interrupting rating (AIR) ensures that even the most severe electrical faults are safely contained, preventing catastrophic equipment failure and expensive downtime.
  • Featuring a true dual-element, time-delay design, this fuse allows a minimum 4-second delay at 500% of its rated current. This prevents nuisance blowing from harmless transient inrush currents during large motor or transformer startups, while still delivering lightning-fast clearing if a damaging short-circuit occurs.
  • Designed with standard bolt-on blade terminals, the KRP-C-800SP ensures a secure, low-resistance physical fit into any standard Class L fuse block or disconnect switch. The precise dimensions eliminate installation guesswork for plant electricians and maintenance crews during routine servicing.
