The TM-D provides L (thermal overload) and I (magnetic short-circuit) protection, so it covers both sustained overcurrents and fault events in one package. At 690 V AC the Icu drops to 45 kA, still substantial for most distribution panels. The 'R' in the breaking capacity code signals this 200 kA class at 415 V. Three poles, 3D protected, with a toggle control and front connections top and bottom. It mounts to a backplate, not a DIN rail — plan for panel cutouts and busbar connections. The 105 mm width and 161 mm height fit the standard NSX100R footprint, so it swaps into existing ComPacT NSX panels without re-drilling.
IP40 front face keeps tools and fingers out; IK07 impact resistance handles incidental knocks during maintenance.
