KLKD.300T Fuse

Product Overview

  • Category: Electrical Component
  • Use: Overcurrent Protection
  • Characteristics: Fast-acting, Time-delay
  • Package: Cartridge
  • Essence: Protects electrical circuits from overcurrent
  • Packaging/Quantity: Typically sold in packs of 10 or 20

Specifications

  • Voltage Rating: 300V
  • Current Rating: 300A

  • Time-delay feature accommodates temporary current surges

Disadvantages

  • May require replacement after a single overcurrent event
  • Can be sensitive to ambient temperature variations

Working Principles

The KLKD.300T fuse operates based on the principle of melting a conductor within the fuse element when subjected to overcurrent conditions. This action interrupts the circuit, protecting downstream components.

Detailed Application Field Plans

  • Industrial machinery
  • Power distribution panels
  • Renewable energy systems
  • Battery protection in electric vehicles

Detailed and Complete Alternative Models

  • Bussmann KTK-R-300
  • Littelfuse KLDR.300
