The Siemens 5SV9316-7NK16 is a SENTRON RCBO — an RCD-operated circuit breaker that combines overcurrent protection and residual current detection in a single 18 mm-wide module. The C-curve means it holds up to 5–10× In for short-duration inrush (typical for motor starters and small transformers) before tripping instantaneously on a hard fault. The 6 kA rating is the same under both standards, so you don't need to derate when specifying across European and international specs.
Depth is 77 mm, installation depth 70 mm — fits standard distribution boards with 80+ mm enclosure depth.
Thermal performance and derating
At 40 °C it derates to 15.2 A, at 45 °C to 14.72 A, at 50 °C to 14.24 A, and at 55 °C to 13.76 A. The 95% humidity tolerance covers damp environments like basements or outdoor-rated enclosures.
