What this MCCB delivers
Its interrupting capacity hits 121 kA at 240 V and 75.6 kA at 415 V — that's the fault-clearing muscle for a main feeder or heavy branch in an industrial panel.
Ratings that matter for fit
The TM240 release means the thermal pickup is fixed at 200 A, with magnetic trip set at 240 A — no interchangeable trip units, so what you see is what protects. The 200 A rating holds flat from 40 °C to 50 °C, then derates to 176 A at 70 °C. Interrupting capacity drops with voltage: 121 kA at 240 V, 75.6 kA at 415 V, 25 kA at 440 V, 11.9 kA at 690 V. For a 400 V line, the 75.6 kA figure is what you compare against your available fault current. The 4-pole construction with 100% N-conductor protection handles three-phase plus neutral without derating the neutral pole.
Built-in undervoltage release
This breaker ships with an integrated undervoltage release (UVR) — part number 3VA9608-0BB11 for the auxiliary trip assembly. That UVR will trip the breaker if supply voltage drops below a threshold, which is standard for motor feeder protection or safety disconnects where you want automatic dropout on undervoltage.
Panel fit and handling
Latching endurance is rated at 15,000 operations, which covers frequent switching in a feeder role.
