MCB & HRC Fuse testing System

SKU: 9573 Category:

Adtron 9573 MCB (Miniature Circuit Breaker) and HRC (High Rupturing Current Capacity) Fuse Testing System is a self contained standalone unit useful for the students of Electrical Engineering to study the behavior and characteristics of MCB and Fuses. The unit consists of 2 different types of MCB’s and 1 HRC Fuse., Variac, Current meter, variable load, Temperature indicator and timer. All this is housed in an elegant metal cabinet with a well spread intelligently designed layout on the front panel. Shrouded terminals are used to avoid direct contact with the live metal parts.
Adtron 9573 provides complete learning contents to demonstrate the internal working of MCB’s and HRC fuse. The MCB’s are provided in transparent case to visualize the internal architectures. Two precise integrated circuit based Thermometers are provided on bimetal contact of MCB’s to analyze the temperature rise and fall.
Digital timer is provided with start and stop facility to study the current versus tripping time characteristics. Inbuilt isolated variable AC Power Supply is provided for safety.

FEATURES:

  • Isolated Power Supply using Transformer
  • Inbuilt variable current injection facility
  • Transparent MCB’s to understand internal architecture and its working
  • Inbuilt Timer, Currentmneter & Temperature indicator
  • MCBs are mounted with temperature sensor for current temperature analysis
  • Equipped with supply indication lamp
  • Shrouded terminals used considering all the safety standards
  • Diagrammatic representation for the ease of connections
