The Siemens SENTRON 5SY6013-6KL is a 1P+N miniature circuit breaker rated 13 A with B tripping characteristic, breaking 6 kA per EN 60898 at 230 V AC. The 18 mm width (1 MW unit) snaps onto standard DIN rail and accepts solid or stranded conductors from 0.75 to 16 mm² at the screw terminals, torqued to 2 to 2.5 N·m.
The 13 A B-curve rating means this breaker trips instantaneously on currents between 3 and 5 times rated (39 to 65 A), designed for resistive or lightly inductive loads like lighting, heaters, or general-purpose sockets where inrush is low.
Halogen-free and silicon-free construction matters in environments where outgassing from a fault could contaminate nearby electronics or process lines.
