The Siemens SENTRON 5SV1313-1GV16 is a 2-pole RCBO (residual current circuit breaker with overcurrent protection) rated 16 A at 30 °C with a Type C tripping characteristic and AC residual current sensing. It occupies a single 18 mm modular width unit on a DIN rail — the standard 1 MW footprint — so it fits a panel already laid out for miniature breakers or RCCBs without re-spacing the rail. Breaking capacity is 4.5 kA per EN 60898 and 5 kA per IEC 60947-2, which covers most commercial and light industrial distribution boards supplied from a transformer of typical impedance. The 5 kA IEC rating gives a bit more headroom for coordination studies where the prospective fault current lands between the two standards.
Thermal derating and mounting
The 16 A rating holds at 30 °C ambient. At 40 °C it derates to 15.2 A, at 50 °C to 14.24 A, and at 70 °C to 12.32 A. If the panel runs warm — say a packed enclosure near a drive or transformer — size the upstream protection for the derated figure at the expected ambient, not the 30 °C nameplate. Mounting position is any, and the supply can enter from either top or bottom, which simplifies busbar routing in a crowded enclosure. Depth is 77 mm (installation depth 70 mm) and height 90 mm. The IP20 rating applies with the distribution board installed and conductors connected — standard for enclosed panel mounting, not for exposed outdoor use.
