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 (transformers, x-ray machines etc, )Short circuit release is set to (10-20)In.
