Circuit protection B, C and D curves
IEC 60898: 6000 A , IEC 60947-2: 10 kA
Function
b The circuit-breakers combine the following functions:
v protection of circuits against short-circuit currents
v protection of circuits against overload currents
v control
v isolation
v protection of persons against indirect contact with TN and IT neutral systems.
C60N circuit breakers are used in the tertiary and industrial sectors.
Tripping curves
24409 B curve
When the short-circuit currents are weak (generators, long cables).
b Power circuit:
v ratings: 1 to 63 A set at 30 °C
v tripping curve: the magnetic trip units operate between 3 and 5 In.
C curve
Cables feeding conventional loads.
b Power circuit:
v ratings: 0.5 to 63 A set at 30 °C
v tripping curve: the magnetic trip units operate between 5 and 10 In.
D curve
24591 Loads with high inrush currents (motors, transformers).
b Power circuit:
v ratings: 0.5 to 63 A set at 40 °C
v tripping curve: the magnetic trip units operate between 10 and 14 In.
