Numerical Single Function Relays : Genesis->
Numerical Non- Directional Overcurrent Protection Relay Type : MIT 103, 104, 113, 114


The MIT over-current combine the power and flexibility of micro-controller technology with decades of experience in the field of protection.MIT has three pole version with two phase & one earth element and four pole version with 3 phase and one earth element.
MIT is housed in a compact 2/3V draw-out vedette case. Settings can be done by a readable Human Machine Interface which also serves for fault indication.


  • Distribution Feeders
  • Transmission Lines
  • AC machines
  • Capacitor banks
  • Transformers
