That makes it a common choice for protecting inductive loads — contactor coils, solenoid valves, small transformers — where the inrush spike is brief but high. Snap-on DIN rail mounting means it clips directly onto a 35 mm symmetrical rail inside the enclosure. The 2-pole width occupies two modular units (36 mm at 18 mm per pole), so factor that into the DIN-rail fill count when laying out the panel. No separate mounting hardware or busbar adapter needed for the rail itself.","metaTitle":"S802S-K50 50A 2-Pole K-Curve MCB, 50 kA, DIN Rail","metaDescription":"S802S-K50 high-performance MCB, 50 A, Trip Curve K, 2-pole, 230 VAC, 50 kA interrupting rating.
