T
Not applicable for Discrimination as these combinations have Ith values or breaking capacities downstream higher than that of upstream CB.
Value
Value Partial Discrimination for which current values are mentioned and the maximum fault current value for which discrimination is ensured.
For fault currents above this value, the 2 circuit breakers trip simultaneously.
T
Total Discrimination, also for all fault current values the circuit breaker CB2 opens and CB1 remains closed.
