What this MCB is and what the ratings mean for fit
The Siemens 5SY6013-7KV26 is a 1+N-pole miniature circuit breaker rated C 13 A, with a 6 kA interrupting capacity at 230 V. The C-curve means it trips between 5 and 10 times rated current — intended for inductive loads like small motors or lighting banks where inrush can exceed the magnetic threshold of a B-curve. The 6 kA SCCR at 230 V tells you it safely clears a fault up to that level without welding the contacts or cascading the arc upstream; that is the standard residential and light-commercial interrupting rating for this class. The 1+N-pole configuration switches both line and neutral, with the neutral pole on the left side of the assembly. Depth is 70 mm, which matches the standard Siemens 5SY series DIN-rail footprint — it snaps onto the same rail as the rest of the panel, no extra adapter needed.
Lifecycle and sourcing reality
For a BOM line that calls out 5SY6013-7KV26, the fit is confirmed by the C 13 A curve and the 1+N-pole neutral-left configuration. Sourced and quoted to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time.
Deployment context
Snap-on DIN-rail mounting means it integrates into a standard panel enclosure alongside other Siemens 5SY series breakers and SENTRON busbar systems. The 1+N-pole neutral-left orientation is worth noting if your panel layout assumes neutral on the right — check the busbar or comb-bridge alignment before committing the assembly.
