It protects a single-phase final subcircuit against overload, short-circuit, and earth leakage. The 1P+N design means it switches the live pole and monitors the neutral; the neutral is not switched but is monitored for imbalance. Thermal derating: 15.2 A at 40 °C, down to 12.32 A at 70 °C.
One modular width (18 mm) means it occupies a single slot in a distribution board. Any mounting position is allowed, so it works in horizontal busbar or vertical DIN-rail layouts. IP20 with connected conductors; the enclosure must be part of a distribution board to maintain the rating.
How it compares to a common sibling
The 5SL6120-7 is a straight MCB (no RCD) in the same SENTRON family, same 1-module width, same C-curve. The 5SV1316-7KK16 adds the residual-current block inside the same footprint — you get earth-leakage protection without giving up a slot. If your BOM already uses the 5SL6120-7 and you need to add RCD protection to that circuit, this RCBO drops into the same panel layout; no rewiring of the busbar position is required, but you do need to connect the neutral through the device. The 5SV1316-7KK16 is the combined solution where the 5SL6120-7 is the breaker-only alternative.
