The C-curve tripping characteristic (5–10× In) handles motor inrush and moderate inductive loads common in industrial control panels. Type F residual current detection covers AC sinusoidal, pulsating DC, and high-frequency AC components — the kind of leakage you get from VFD-fed motors, switched-mode supplies, and modern LED drivers. That makes this unit a better fit for mixed-load final subcircuits than a standard Type A RCBO. Depth of 77 mm (70 mm installation depth) fits most distribution boards. ## Breaking capacity and thermal derating At 40 °C it derates to 23.5 A; at 50 °C to 21.75 A; at 60 °C to 20.25 A; at 70 °C to 18.25 A. ## Mounting and wiring notes Mounting position is any — vertical, horizontal, or upside-down on the DIN rail. Supply feed can enter from top or bottom, which simplifies busbar routing in multi-row boards. Touch protection is built in (finger-safe terminals).","metaTitle":"Siemens 5SU1354-4KK25 SENTRON RCBO, 2P, 25 A, 30 mA, Type F,","metaDescription":"Siemens SENTRON 5SU1354-4KK25 RCBO, 2-pole, 25 A, 30 mA residual current, Type F, C-curve, 10 kA per EN 60898.
