| Parameter | Description | Formula / Value | Notes |
|---|---|---|---|
| Prospective Short-Circuit Current (Isc) | Maximum fault current at MCCB terminals | Isc = Vph / Ztotal | Vph: phase voltage (Volts), Ztotal: total impedance (Ohms) |
| Ultimate Breaking Capacity (Icu) | Maximum short-circuit current MCCB can interrupt without damage | Value from ABB MCCB datasheet (e.g., 25 kA, 36 kA, 50 kA) | Check model-specific ratings |
| Service Breaking Capacity (Ics) | Guaranteed interrupting capacity under specified conditions | Typically 70% or 100% of Icu | Depends on manufacturer specification |
| Maximum Breaking Time (Tmax) | Maximum time to interrupt a fault current | Specified in breaker datasheet (milliseconds) | Related to trip curve settings |
| Energy Let-Through (I²t) | Energy dissipated during fault interruption | I²t = If² × Tmax | If: fault current (Amps), Tmax: breaking time (seconds) |
