The Siemens SENTRON 5SL6213-7BB is a 2-pole miniature circuit breaker rated 13 A with a C tripping characteristic, designed for 400 V AC residential and infrastructure circuits. Its 6 kA breaking capacity per EN 60898 and IEC 60947-2 handles typical branch-circuit faults in panelboards and distribution boards without cascading upstream.
What the ratings mean for fit
The C-curve means the magnetic trip threshold is 5 to 10 times rated current — suited for mixed resistive and moderate inductive loads like lighting, small motors, and socket circuits where inrush is not extreme. The 6 kA breaking capacity is the maximum prospective fault current the breaker can safely interrupt at 400 V; for installations with higher available fault current (e.g., near large transformers), a higher-rated breaker or upstream current-limiting device is needed. The 2-pole design switches both phase and neutral on a single-phase circuit or one phase of a three-phase system; it occupies 2 modular width units (36 mm) on a DIN rail.
Deployment context
Snap-on DIN-rail mounting (: any position) fits standard 35 mm rail in distribution boards and subpanels. IP20 with connected conductors means it is protected against finger contact but not against moisture — suitable for dry indoor enclosures only. The 76 mm depth and 70 mm installation depth leave clearance for wiring and busbar connections in typical 100 mm deep enclosures.
