The interrupting rating hits 121 kA at 240 V, 75.6 kA at 415 V, and 52.5 kA at 440 V — figures that govern fault-current coordination downstream.
At 40 °C the breaker carries a full 100 A; at 55 °C it derates to 98 A, at 70 °C to 91 A. That means a panel ambient of 50 °C still allows the full 100 A rating — no upsizing needed for typical enclosed switchgear.
Auxiliary release and monitoring
The breaker has no trip indicator, no voltage trigger, and no ground-fault monitoring — the TM210 release handles overcurrent only, so any ground-fault protection must come from an external relay or an upstream RCD.
