The interrupting capacity reaches 330 kA at 240 V, 242 kA at 415/440 V, 187 kA at 500 V, and 52.5 kA at 690 V — figures that cover most industrial fault levels without cascading upstream.
The 200 A rating holds across 40–50 °C ambient; above that it derates to 192 A at 55 °C, 188 A at 60 °C, 184 A at 65 °C, and 180 A at 70 °C. The ETU350M release provides phase-failure detection and a voltage trigger, so it will trip on loss of phase or overvoltage — critical for motor circuits where single-phasing burns windings. The shunt trip (STL) allows remote tripping from an E-stop or PLC output.

Dimensions are 105 mm wide × 181 mm high × 86 mm deep — standard SENTRON 3VA2 footprint for a 3-pole frame. Maximum power loss is 75 W, so allow ventilation around the breaker in a sealed enclosure.
