Eaton Bussmann KTK-R-30 Low Voltage Fuse

Eaton Bussmann KTK-R-30 Low Voltage Fuse

The Eaton Bussmann Series Class CC KTK-R fuse, model 30 A, is a fast acting, dual element current limiting fuse designed specifically for circuit protection. Here is a detailed introduction to this fuse:

Product Overview

The Eaton Bussmann KTK-R series Class CC fuses are renowned for their advanced protective performance, providing 10 times faster short-circuit protection than basic circuit breakers or fuses. This 30 A fuse, with its fast response and current limiting characteristics, helps prevent equipment damage caused by short circuit events.

Core Features

• Quick action protection: KTK-R series fuses provide quick action protection, effectively limiting short-circuit current and reducing damage to equipment.
  
• Current limiting characteristics: Class CC level current limiting performance provides maximum short-circuit current protection for components.
  
• Rejection Function: Class CC rejection function, combined with appropriate fuse holders, prevents the insertion of auxiliary fuses with low ratings, ensuring that the circuit is properly protected.
  
• High interrupt rating: 200kA interrupt rating, in compliance with NEC ® The requirements of Section 110.9 apply to today's high-capacity systems.

Application Fields

The KTK-R 30 A fuse is suitable for special circuits, industrial controls, and isolated, inline fuse holders (such as street lighting).

Technical Specifications

• Rated current: 30 A
  
• Voltage level: 600Vac
  
• Interruption capability: 200kA RMS Sym 
  
• Size: 13/32 "x 1-1/2" (10.3 x 38.1mm)
