Its interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V, and 76 kA at 440 V — numbers that matter when you're coordinating with upstream gear in a high-fault panel. The TM240 thermal-magnetic release handles line protection, and the built-in undervoltage release (UVR) lets you drop the breaker on a control signal or safety circuit.
Full 16 A rating holds from 40 °C through 55 °C ambient; at 60 °C it derates to 15 A and stays there through 70 °C. That's a clean thermal curve — no surprise drop at 50 °C. The 130 mm height and 4 in width fit standard SENTRON panel layouts;
