Breaking capacity and what it means for your fault study
At 240 V this MCCB interrupts 187 kA; at 415 V it still holds 121 kA, and at 440 V it manages 75.6 kA.
Thermal derating — the real continuous current
Above that, the continuous current derates: 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, and 114 A at 70 °C. If your panel ambient runs at 60 °C, you lose 5 A — plan your load accordingly.
Auxiliary and release configuration
The two auxiliary switches provide status feedback (open/closed) to a PLC or indication lamp. No ground-fault monitoring or communication function on this variant.
