The Siemens 5SL6414-7CC is a 4-pole miniature circuit breaker rated for 400 V AC with a 6 kA breaking capacity. It carries a C-trip curve and is set at 0.3 A, making it suitable for protecting smaller branch circuits or control transformers where moderate inrush tolerance is needed. The 4-pole configuration covers three phases plus neutral in a single module, simplifying DIN-rail panel layout.
No last-time-buy or successor notice applies.
The 4-pole body occupies 4 module-widths (72 mm at 18 mm per pole), so account for that fill factor when laying out a sub-distribution board. The C-curve (5–10× In magnetic trip) handles motor-start inrush or transformer energization without nuisance tripping, while the 0.3 A rating limits the protected load to fractional-horsepower motors or small control circuits.
RoHS compliant since June 2013. REACH Article 33 disclosure notes lead (CAS 7439-92-1) above 0.1% w/w in one component; this is standard for certain internal alloy parts and does not affect the breaker's functional compliance with the RoHS directive.
