The Siemens 5SU1353-6KV16 is an FI/LS combination unit — a residual-current circuit breaker with integral overcurrent protection (RCBO) — in a single 1+N-pole module. Its Type A (PSE/SSF) sensitivity detects sinusoidal AC and pulsating DC fault currents, with a rated residual operating current (IΔn) of 30 mA and a short-circuit breaking capacity of 4.5 kA. The thermal-magnetic release is calibrated to B-curve characteristics at 16 A, so it trips between 3 and 5 times rated current for fast protection of resistive and light inductive loads.
