Dimensions and DIN-rail fit
The 5SJ6513-6KS occupies 2 modular width units (36 mm) on a standard DIN rail, with a body depth of 76 mm and an installation depth of 70 mm. Height is 90 mm. If this breaker lives inside a panel that gets hosed down, you'll want a separate enclosure.
That -40 °C floor matters for unheated utility rooms or outdoor kiosks in cold climates — the breaker still trips reliably when it's freezing. Halogen-free and silicon-free construction reduces corrosive off-gassing in a fire, which is a plus for telecom or data-center installs. Degree of pollution 2 and overvoltage category 3 are standard for fixed-installation MCBs. Sealable design lets you lock the toggle position for lockout/tagout procedures. Touch protection is built in — no exposed live parts when the breaker is mounted.
Sourcing this part for a BOM line
The 5SJ6513-6KS carries an active lifecycle status, meaning Siemens continues to manufacture it without a last-time-buy notice. For a production BOM or a panel shop's standard build, this is a straightforward line item — no substitution or obsolescence risk on the horizon. We source it through independent distribution channels and quote firm pricing and availability against an RFQ. If you're freezing a BOM for a multi-year run, this is a safe pick.
