Breaking capacity is 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. Current rating holds flat at 100 A from 40 °C through 50 °C ambient, then derates gradually to 90 A at 70 °C.
The 105 mm width fits standard distribution panel layouts.
If your motor draws 95 A FLA, this breaker holds at 100 A with headroom; if your ambient hits 70 °C, the 90 A derated figure still covers it. Starter protection version means the trip unit is configured for motor-starting duty — it tolerates the inrush without nuisance tripping on the thermal curve while still providing short-circuit protection. The ETU310M is an electronic trip unit with adjustable settings; the base switch supplied is the 3VA2110-7MS36-0AA0.
