Tripping characteristics

  • Based on the Tripping Characteristics, MCB are available in“B”,“C”and“D”curve to suit different types of applications.
  • “B”Curve for protection of electrical circuits with equipment that does not cause surge current (lighting and distribution circuits) Short circuit release is set to (3-5)In.
  • “C”Curve for protection of electrical circuits with equipment that cause surge current (inductive loads and motor circuits) Short circuit release is set to (5-10)In.
  • “D”Curve for protection of electrical circuits with cause high inrush  current ,typically 12-15 times the thermal rated current (transformes, x-ray machines etc,)Short circuit release is set to (10-20)In.
