Based on the Tripping Characteristics, MCBs are available in “B”, “C” and “D” curve to suit different applications.
“B” Curve - for protection of electrical circuits with equiptment 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 equiptment that causes surge current (inductive loads and motor circuit) Short circuit release is set to (5-10)In.
“D” Curve - for protection of electrical circuits which 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.
