The device features a C-trip characteristic, which provides stable protection for loads with moderate inrush currents typical in automation controllers. This translates to fewer nuisance trips during startup while preserving personnel and equipment safety in DC control circuits. The 250 V DC rated voltage and 440 V AC operating range ensure compatibility across mixed voltage rails found in industrial panels, enabling flexible design without additional protective devices. With a 1P, 0.5 A rating and a 10 kA short-circuit capacity, it delivers targeted protection for small-control circuits while tolerating high fault currents, reducing the likelihood of cascading failures in the broader system. Built to mount on DIN rails (TH35) and compatible with Ring-Tongue terminals, installation is quick, repeatable, and less error-prone, which lowers commissioning time and labor costs. The 69 mm built-in depth and 17.5 mm width keep panel footprints compact, while energy-limiting class 3 and 1.3 W power loss support energy-efficient operation in dense automation environments. RoHS and REACH compliance, along with a CE declaration, ensure regulatory alignment and easier procurement for modern factories. The device’s 20,000 mechanical cycles and IP20 protection provide durable reliability in everyday industrial use, reducing spare parts inventory and downtime. Its universal mounting position and clear ON/OFF indication help technicians diagnose and service the unit quickly, even in crowded switchgear rooms. The S200MTR lineage and documented manuals support faster troubleshooting and safer maintenance routines, driving long-term cost savings and improved asset utilization.
