At 55 °C — the top of the operating range — it's 17.4 A. Power loss is 3.8 W maximum, which matters when packing multiple RCBOs in an enclosure — heat buildup accelerates the derating curve. ## Wire termination and physical fit That covers most final subcircuit wiring — 1.5 mm² for lighting, 2.5 mm² for socket outlets, 4 mm² or 6 mm² for heavier loads, and 10/16 mm² for submain feeds where an RCBO is used as a main switch. Depth is 77 mm, installation depth 70 mm, height 90 mm. The 18 mm width equals one modular unit (1 MW), so it occupies a single pole position on a DIN rail.","metaTitle":"Siemens 5SV9316-1NK20 SENTRON RCBO, 20A C-curve, 6kA, 1P+N","metaDescription":"Siemens 5SV9316-1NK20 SENTRON RCD-operated circuit breaker, 20 A rated, C tripping characteristic, 6 kA breaking capacity, 1P+N, 18 mm wide.
