 Project Synopsis
FOX Veri – Mac 1 is the world’s fastest thermal trip verification machine for MCBs.

The machine is ergonomically designed and intelligently automated to deliver 1800 poles / hr with only one operator. Interestingly it also has one of the smallest footprints in the industry.

The machine tests Legrand’s Lexis series of MCBs / RCB poles ranging from 6 Amp to 63 Amp.

All test records are archived. Records can be filtered on shift /date / current range etc. The HMI is very user friendly. Trends of first pass yield, second pass yield, statistical information for QA like Cp, Cpk, Standard Deviation, etc are easily accessible.

The scope of work included:

  1. Machine concept development and FDS
  2. Mechanical and electrical design of machine.
  3. Machine building
  4. Software development
  5. Commissioning and Performance trials
