It's a 3-pole, 200 A frame with a TM120M thermal-magnetic trip unit, meaning the thermal element handles overloads and the magnetic element clears short-circuits. The 200 A rating holds flat from 40 °C up to 50 °C, then derates linearly to 176 A at 70 °C — so in a warm panel you still get the full 200 A up to 50 °C ambient. Breaking capacity is the headline here: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 4.5 kA at 690 V.
Built-in undervoltage release and what that means for your circuit
That's standard for motor starter applications where you want the breaker to open on a loss of control power, preventing an automatic restart when power returns. The UVR is wired to the control circuit, not the power path. On a DIN-rail or panel-mount installation, you'll run a separate pair from the control transformer or PLC output to the UVR terminals. No communication function on this unit — it's a standalone electromechanical trip, no Modbus or PROFIBUS interface. Physical footprint: 105 mm wide, 158 mm tall, 70 mm deep. That's a standard 3-pole MCCB width for a 200 A frame — it'll fit existing SENTRON mounting bases and busbar systems without panel rework.
