Above 50 °C it steps down: 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C — so if your panel runs hot, the 100 A frame still carries 90 A at the top of its operating range. The interrupting ratings are the headline here: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 52.5 kA at 690 V. This is the starter protection version, designed to sit ahead of a motor starter. The ETU310M electronic overcurrent release handles coordination, and the integrated undervoltage release drops the breaker on loss of control voltage.
No auxiliary contacts fitted from the factory (auxiliary contact version: without), and no communication function or phase failure detection. If you need remote status or phase-loss tripping, you'll add the external auxiliary trip (3VA9608-0BB11) or a separate monitoring relay. The basic switch assembly is order code 3VA2110-7MS36-0AA0 — the same breaker minus the UVR coil.
What it does not do
No trip indicator, no voltage-trigger function, no ground-fault monitoring built in. Maximum power loss is 75 W.
