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
  • Interrupting Rating: 200kA

Detailed Pin Configuration

  • The fuse has two metal end caps with a cylindrical body. One end cap is typically marked as the line side and the other as the load side.

Functional Features

  • Fast-acting response to overcurrent conditions
  • Time-delay feature for handling temporary overloads
  • High interrupting rating for safety

  • Provides reliable overcurrent protection
  • Fast response helps prevent damage to equipment
  • 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

This information provides a comprehensive overview of the KLKD.300T fuse, covering its category, use, characteristics, specifications, pin configuration, functional features, advantages and disadvantages, working principles, application field plans, and alternative models.
