The Siemens 5SL6016-7KL is a SENTRON miniature circuit breaker (MCB) in a compact 1P+N design with two poles, switching both phase and neutral. Rated 16 A at 230 V AC with a C tripping characteristic, it provides 6 kA breaking capacity per EN 60898 — sufficient for residential and light commercial distribution boards where the prospective short-circuit current stays under that threshold. The 18 mm width (one modular unit) snaps onto standard DIN rail and accepts any mounting position, which simplifies panel layout.
What the ratings mean for fit
The C-curve (tripping characteristic class C) means the magnetic trip operates at 5 to 10 times rated current — typical for mixed resistive and moderate inductive loads like lighting circuits, small motors, and socket outlets. The 6 kA breaking capacity at 230 V AC per EN 60898 certifies it for use in final circuits where the fault level does not exceed that value. Overvoltage category III and pollution degree 2 suit fixed-installation distribution boards inside buildings. Thermal derating is published for ambient temperatures above 30 °C: 15.04 A at 40 °C, 14 A at 50 °C, and 12.89 A at 60 °C. If the panel runs hot — near a transformer or in a sealed enclosure — size the upstream protection against the derated figure, not the 30 °C nameplate.
Integration and compliance
The MCB mounts on DIN rail with a depth of 76 mm and an installation depth of 70 mm — verify enclosure depth clearance if the panel has a shallow backplate. The housing is halogen-free and silicon-free, which matters for clean-room or corrosive-environment installations. Touch protection is integrated, and the neutral conductor is switched (1P+N design). Sealable terminals allow lockout/tagout for maintenance isolation. Rated IP20 with connected conductors — suitable for dry indoor enclosures only, not washdown or outdoor exposure. Vibration resistance per IEC 60068-2-6 is confirmed, so it holds up in panels mounted on machinery or in transport applications.
