Its 10 kA interrupting rating per EN 60898 tells you it can safely clear a fault up to 10,000 A at 400 V without welding contacts or venting plasma — essential for panel coordination in residential and light commercial infrastructure.
At 40 °C it derates to 15.15 A; at 50 °C to 14.26 A; at 55 °C to 13.79 A.
Mounts in any position. IP20 with conductors connected; touch-protected terminals. Rated for ambient -40 °C to 75 °C, 95% humidity at 55 °C max.
Listed as current production (active lifecycle). No end-of-life notice, no successor announced. This is a standard catalog SKU in the SENTRON 5SL family — the one you can specify into a BOM and expect to buy for the next several years without a last-time-buy scramble.
