Mounts in any position, takes 2 width units on the DIN rail, and its 70 mm installation depth fits standard enclosures. Conductor range covers 0.75 to 35 mm² solid or stranded, with screw terminals torqued to 2.5–3 N·m. At 25 A it'll hold a 5.5 kW motor start-up without nuisance tripping, but still clears a hard fault fast. The 30 mA type A residual detects pulsating DC fault currents — common on variable-frequency drives, LED drivers, and switched-mode supplies — which a plain AC type would miss. In a panel with a large upstream transformer, that's the difference between a coordinated trip and a cascade failure. The energy limiting class 3 rating tells you it restricts let-through energy to a low level, protecting downstream wiring and connected loads. Rated for ambient temperatures from -25 to +55 °C with up to 95% humidity, and storage from -40 to +75 °C. Overvoltage category III means it's designed for fixed-installation panels, not just socket-outlet circuits. The 1 kA surge current resistance (8/20 µs wave) handles lightning-induced transients typical in industrial buildings. Touch protection is built in (finger-safe terminals per the spec), which saves time on panel labeling and inspection sign-off.","metaTitle":"SENTRON 5SU1322-7KC25 RCBO, 2P, 25 A, C, 30 mA, 50 kA","metaDescription":"SENTRON 5SU1322-7KC25 RCBO, 2-pole, 25 A, C-curve, 30 mA type A, 50 kA breaking capacity.
