The Siemens 5SU1354-7KV10 is a combined residual-current and miniature circuit breaker (RCBO) — an FI/LS protector Type A (PSE/SSF) — rated at IΔn 30 mA, 10 kA breaking capacity, 1+N-pole, C characteristic, 10 A. It integrates earth-leakage and overcurrent protection in a single 70 mm-wide module for DIN-rail enclosures.
What the ratings mean for fit
Type A detection trips on AC sinusoidal residual currents plus pulsed DC. The 30 mA sensitivity protects against direct-contact shock.
