The Siemens 5SN1 N L16A is a 1-pole miniature circuit breaker (MCB) from the 5SN1 series, rated at 16 A and 220/380 V. This is the part number for a single-pole branch-circuit overcurrent protection device, sized for lighting, receptacle, and light motor loads in a 220/380 VAC system. The 16 A rating means it will trip on sustained overload above that threshold and on short-circuit fault current — the thermal-magnetic mechanism inside clears the fault without needing a separate fuse.
