Ratings and what they mean for your panel
The Siemens 5SL4413-7CC is a 4-pole miniature circuit breaker rated 13 A, C-curve, with a breaking capacity of 10 kA at 400 V. The C-curve means the magnetic trip operates between 5 and 10 times the rated current — suited for general-purpose loads like lighting, socket outlets, and small motor circuits where inrush is moderate. The 10 kA breaking capacity at 400 V tells you it can safely interrupt a fault current up to that level without welding the contacts or cascading failure upstream, which is the standard domestic and light commercial rating for this class per EN 60898. The 4-pole configuration (all three phases plus neutral switched) makes it a fit for three-phase final subcircuits where you need full isolation of the neutral as well as the line conductors — typical in TN-S or TT systems where the neutral is not solidly bonded at the distribution board.
Lifecycle and sourcing reality
Note the product class B restriction: return is restricted, so the buyer should confirm the order code and quantity before committing. This is a standard Siemens policy for certain MCB families, not a sign of obsolescence. RoHS compliance is confirmed effective 01-06-13. REACH candidate-list information is available per the manufacturer. No UL or CSA listing appears in this evidence — verify local code acceptance if the installation requires third-party certification beyond CE/UKCA.
Integration into the distribution board
This is a DIN-rail mount device, 4-pole width (roughly 72 mm for the 4-module footprint). The spring-cage or screw terminals accept standard copper conductors per the 5SL series practice — strip length and torque values follow the manufacturer's mounting instructions. No special busbar or comb is required beyond the standard 10 mm pitch.
