The 1P+N pole configuration switches the line conductor and provides a switched neutral — the neutral is opened and closed with the line, not just solidly connected. This matters where you need isolation of both poles for maintenance or where local code demands a switched neutral on single-phase final circuits. The single width unit means it occupies 18 mm of DIN-rail space, so it fits a standard 18 mm-per-pole panel layout. ## Panel integration and environment Degree of pollution 2 and overvoltage category III confirm it is rated for the fixed-installation environment typical of building electrical distribution. Ambient temperature range is -40 to +75 °C for storage and operation, though the surrounding temperature influence note specifies periodic exposure to +55 °C at max 95% humidity — typical for an unventilated enclosure in a warm climate. Halogen-free and silicon-free construction means the materials do not release corrosive halogen gases under fire, which is a requirement for equipment installed in ventilated or occupied spaces where off-gassing could damage adjacent electronics or harm personnel.","metaTitle":"Siemens 5SY6016-6KL SENTRON MCB, 1P+N B-16A 6kA 230V","metaDescription":"Siemens 5SY6016-6KL SENTRON miniature circuit breaker, 1P+N, B-curve, 16 A, 6 kA per EN 60898, 230 V AC.

The functional difference is the tripping characteristic: 5SY6016-6KL is B-curve, while 5SY6020-7KL is C-curve. The C-curve (magnetic trip at 5–10× In) is for loads with higher inrush, like small motors or transformers. If the panel was designed for C-curve, substituting a B-curve may cause nuisance tripping on start-up. Check the load type before swapping."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SY6016-6KL","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/5SY6016-6KL when reusing this data.
