It protects a single-phase final subcircuit against both overload/short-circuit and earth leakage, with a 10 A rated current, C-trip curve, and 30 mA type A residual sensitivity.
Snaps onto DIN rail (EN 60715) in any mounting position, occupying 2 MW at 36 mm wide. Rated IP20 with conductors connected and the distribution board installed, so it's intended for enclosed use only.
The 30 mA type A residual detects pulsating DC fault currents as well as sinusoidal AC, covering modern electronics and variable-speed drives downstream. Energy limitation class 3 keeps let-through energy low, protecting downstream wiring and connected equipment during a fault.
The nearest functional peer is the 5SU9354-7KK16, which shares the same 1P+N pole configuration, C-curve, 30 mA type A sensitivity, and identical 77×36×90 mm footprint. The key difference: the 5SU9354-7KK16 carries a higher 10 kA breaking capacity under both EN 60898 and IEC 60947-2, versus the 5SU1356-7GV10's 6 kA / 15 kA split. If your panel's prospective fault current exceeds 6 kA at the point of installation, the 5SU9354-7KK16 is the safer drop-in. For standard domestic or light commercial distribution boards where 6 kA is adequate, the 5SU1356-7GV10 is the economical fit.
