It breaks faults up to 15 kA per EN 60898 or 50 kA per IEC 60947-2 — the higher figure applies when the installation follows IEC 60947-2, which is typical for industrial control panels rather than residential distribution boards. ## Thermal derating and environment Rated 1.6 A at 35 °C, derated to 1.54 A at 40 °C, 1.5 A at 45 °C, 1.47 A at 50 °C, 1.44 A at 55 °C, and 1.4 A at 60 °C. Humidity tolerance: 95% RH up to 55 °C, 55% RH up to 70 °C, 35% RH up to 75 °C. Sealable, halogen-free, silicon-free.
