At 16 A it handles continuous resistive loads at 35 °C; derate to 15.02 A at 40 °C, 14.51 A at 45 °C, and so on down to 12.86 A at 60 °C. The 15 kA (EN 60898) rating covers the domestic/commercial branch circuit fault level; the 25 kA (IEC 60947-2) rating applies when the breaker is used in an industrial distribution board with higher prospective short-circuit current. That extra headroom means you don't need an upstream current-limiting fuse in many panels — check the SCCR of the whole assembly, but the breaker itself is good for 25 kA.
