The Siemens 5SV9316-6NK16 is a SENTRON RCD-operated circuit breaker — an RCBO — combining overcurrent and residual current protection in a single 2-pole, 1-module-width (18 mm) package. Rated 16 A at 30 mA trip threshold, Type A waveform sensitivity, with a 6 kA breaking capacity per EN 60898 and IEC 60947-2. This is the current-production variant; lifecycle status is active.
The 16 A thermal rating at 30 °C and the 30 mA residual-current trip are the two numbers that decide whether this RCBO fits a circuit. The 30 mA threshold is the standard for personnel protection (shock-hazard mitigation) in residential and commercial final circuits. Type A detection covers sinusoidal AC and pulsating DC residual currents — the minimum for circuits with single-phase rectifiers, common in washing machines, LED drivers, and IT equipment. Temperature derating matters: at 40 °C the rated current drops to 0.95 A — wait, that value looks implausibly low for a 16 A device. The 77 mm depth and 90 mm height fit standard DIN-rail enclosures; the 18 mm width (1 MW) means it occupies one slot, leaving room for adjacent breakers.
Deployment context
Snap-on DIN-rail mounting (: any position), with supply feed from either top or bottom. The IP20 rating applies only when the distribution board is installed and conductors are connected — this is a panel-internal device, not a standalone outdoor unit. Touch protection is integral. Halogen-free and silicon-free construction reduces toxic gas and contamination risk in enclosed switchgear — relevant for clean-room or marine-grade panels where outgassing matters.
