What this RCBO is and what the ratings mean for fit
The Siemens 5SV1316-7KK16 is a SENTRON RCBO — a combined residual-current device and miniature circuit breaker in one 18 mm-wide, 1-module package. 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. This is the compact go-to for residential and light commercial distribution boards where panel space is tight and you need both overcurrent and earth-leakage protection in a single slot. Rated 16 A at 30 °C with a C-curve tripping characteristic. Thermal derating: 15.2 A at 40 °C, down to 12.32 A at 70 °C. Breaking capacity: 6 kA per EN 60898 for the domestic standard, and 10 kA per IEC 60947-2 for industrial coordination. That 10 kA figure is what matters for commercial panel SCCR calculations — it tells you the device can safely interrupt a fault up to 10 kA at 230 V without welding or rupturing. Overvoltage category III and pollution degree 2 confirm it's rated for fixed-installation distribution boards, not plug-in portable gear.
Panel integration details
Snaps onto standard 35 mm DIN rail. One modular width (18 mm) means it occupies a single slot in a distribution board. Installation depth is 70 mm behind the panel face; total depth including the front is 77 mm. Supply can enter from top or bottom — no mandatory orientation. 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. Halogen-free and silicon-free construction — relevant for clean-room or corrosive-environment specs where outgassing matters.
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.
