The 'starter protection' designation means its trip curve is shaped to coordinate with motor contactors and overload relays, so it clears a bolted fault without letting the contactor weld shut. That 200 A holds flat from 40 °C through 50 °C; above 55 °C it derates to 192 A, then 188 A at 60 °C, 184 A at 65 °C, and 180 A at 70 °C — useful to know if the breaker lives in a hot enclosure near the motor starter.
This MCCB carries 220 kA at 240 V, 154 kA at 415 V, 36 kA at 440 V, and 17 kA at 690 V. Those are the interrupting ratings at each voltage level — the current it can safely extinguish an arc at. In a 415 V distribution panel with a transformer upstream that can deliver 100 kA fault current, this breaker sits comfortably below its 154 kA ceiling, so no cascading failure if a downstream short occurs. At 690 V the 17 kA rating still covers most industrial motor-drive bus faults.
The breaker measures 105 mm wide, 158 mm high, 70 mm deep — a standard SENTRON 3VA frame size for 200 A.
