The Siemens 5SL6302-7BB is a SENTRON miniature circuit breaker (MCB) — a 3-pole, C-curve unit rated 2 A at 400 V AC, 50 Hz, with a 6 kA breaking capacity per EN 60898 and IEC 60947-2.
Rated 2 A at 30 °C ambient, but that number drops as the panel warms up: 1.92 A at 40 °C, 1.88 A at 45 °C, 1.79 A at 55 °C. If your panel runs hot, the 30 °C rating isn't the one to spec by — use the derated figure for your actual ambient. Mechanical life is 10 000 switching cycles typical.
