It integrates a 16 A B-curve miniature circuit breaker with a 300 mA residual-current trip into a single 1+N-Pol module. The 4.5 kA short-circuit capacity covers the majority of domestic and light commercial final circuits where the prospective fault current stays under that threshold. Type AC detection means it responds to sinusoidal AC residual currents only — not pulsed DC or smooth DC — so it is suited for circuits without electronic loads that generate DC fault components.","metaTitle":"Siemens 5SU1653-0KV16 FI/LS Protector, Type AC, 16A, 300mA,","metaDescription":"Siemens 5SU1653-0KV16 FI/LS protector, Type AC, 16A B-curve, 300mA, 4.5kA.
