The Siemens 5SL6201-7YA is a 2-pole miniature circuit breaker (MCB) rated 230 V with a 6 kA breaking capacity, C-curve trip characteristic, and 1 A rated current.
Snap-on DIN rail mount for standard TH35 profile. The 2-pole width occupies two modular units (36 mm). When populating a high-density distribution board, account for thermal derating when multiple breakers are ganged side-by-side without spacing — the 1 A rating assumes 30 °C ambient; above that, reduce load per the manufacturer's derating curve.
