The C253TM200D is a thermal-magnetic trip unit from the Schneider Electric ComPacT NSX100...250 DC range, rated 200 A at 40 °C for DC distribution networks. It's built to EN/IEC 60947-2, so it's a certified DC breaker component for industrial panels. The 3P 3d configuration protects all three poles, and the TM-D trip unit gives you LI protection — thermal overload (L) and magnetic short-circuit (I). That 750 V DC rated operational voltage means it handles the bus voltage in most DC traction or solar combiner setups without a sweat. This trip unit is meant for distribution applications, not motor protection — the fixed long-time delay (tr) and adjustable Ir (0.7 to 1 x In) and Ii (5 to 10 x In) give you the curves for feeder protection. The IP40 rating keeps dust and small debris out, fine for a clean panel environment.
