Product details

The headline number for a sourcing decision is the interrupting capacity: 187 kA at 240 V, 121 kA at 415 V, 30 kA at 440 V, and 17 kA at 690 V. The thermal-magnetic release is a TM120M, sized for motor and starter protection duty. The 200 A rating holds flat from 40 °C through 50 °C (200 A at each), then derates to 192 A at 55 °C, 188 A at 60 °C, 184 A at 65 °C, and 180 A at 70 °C. For a panel builder, that means no headroom loss in a typical 40 °C enclosure — but if the ambient inside the cabinet runs above 50 °C, you lose roughly 2 A per 5 °C rise. Front protection is IP40, so it's sealed against tool entry but not washdown.

Integration and auxiliary hardware

The integrated auxiliary trip is order code 3VA9608-0BB11. The operating power at AC-3 duty at 400 V is 75 W — that's the motor-switching capability under the starter protection version. For a site electrical engineer, the key takeaway: this breaker is built for motor branch circuits where the TM120M release provides the thermal memory for starting inrush and the magnetic trip for short-circuit protection, not for pure distribution feeder duty.
