Eaton Bussmann LP-CC-4-1/2 Low Voltage Fuse

Eaton Bussmann LP-CC-4-1/2 Low Voltage Fuse

The Eaton Bussmann Series Class CC LP-CC fuse, Model 4.5 A, is a high-performance current limiting delay fuse designed specifically to provide circuit protection. Here is a detailed introduction to this fuse:

Product Overview

The Eaton Bussmann Series Class CC LP-CC fuse, 4.5 A model, has set a new standard in the field of circuit protection with its outstanding performance and reliability. This fuse combines time delay and Class CC current limiting response to provide precise protection for small motors and relay circuits, while maximizing the short-circuit current rating protection of the components.

Core Features

• Current limiting delay protection: LP-CC fuses provide a time delay of at least 12 seconds, suitable for 200% of rated current, effectively avoiding unnecessary melting caused by surge current, while providing fast response and high current limitation under fault conditions.
  
• High and medium break ratings: This fuse has a DC break rating of 20kA (150Vdc) and an AC break rating of 200kA (600Vac), ensuring the safety of the circuit under extreme short-circuit conditions.
  
• Refusal function: Class CC refusal function, combined with appropriate fuse holders, prevents the insertion of auxiliary fuses with low ratings, thereby ensuring the correct protection of the circuit.
  
• Size and Installation: The size of the LP-CC fuse is 13/32 "x 1 1/2" (10.3 x 38.1mm), with a compact design that is easy to install.

Application Fields

LP-CC fuses are suitable for special circuits, industrial controls, and isolated, inline fuse holders, especially in situations where there is high starting current in the circuit (such as motor/transformer loads).

Technical Specifications

• Rated current: 4.5 A
  
• Voltage level: 600Vac and 300Vdc
  
• Interruption capability: 200kA RMS Sym (AC) and 20kA DC (DC)
  
• Response time: At least 12 seconds at 200% rated current
  
• Certification: UL ®, CE, CSA ® Certified.

Advantages

• Selective Coordination: LP-CC fuses provide a 2:1 selective coordination ratio within the Low Peak fuse family, preventing unnecessary circuit shutdowns from extending beyond the fault circuit.
  
• Inventory consolidation: 13/32 x 1 1/2 inch supplementary fuses reduce SKU investment and minimize the potential for incorrect fuse application.

Summary

The Eaton Bussmann Series Class CC LP-CC-4-1/2 fuse provides a reliable solution for various circuit protection needs due to its time limiting characteristics, high and medium break ratings, and compact size. This fuse not only responds quickly, but also effectively protects the circuit from damage, making it an ideal choice for low horsepower motor circuits and control applications.
