Rated breaking capacity is 25 kA per IEC 60947-2, which covers most industrial panel fault levels. For UL 1077 / CSA C22.2 No. 235 installations, the rating is 5 kA — that's the figure to use when the panel is built to North American code. Overvoltage category III, so it's rated for fixed-installation distribution boards, not just branch circuits. ## D-curve — what it means on the line The D characteristic (tripping between 10× and 20× In) is the right choice for loads with high inrush — motor starters, small transformers, solenoid banks. That's the main selection criterion: if the downstream load is resistive or general-purpose, a C curve might be cheaper; if it's inductive with a heavy start, the D curve saves callbacks. Width is 18 mm (1 MW), so it occupies one position on a DIN rail. The quick-assembly mounting system clips onto the rail without tools. Rated ambient temperature -25 to +55 °C, storage -40 to +75 °C. Mounting position any, so it can be installed horizontally in shallow enclosures without derating the current. The part is also touch-protected (finger-safe terminals).","metaTitle":"Siemens SENTRON 5SY7116-8CC MCB, 1P D 16 A, 25 kA IEC","metaDescription":"Siemens SENTRON 5SY7116-8CC miniature circuit breaker, 1-pole, D-curve, 16 A, 400 V AC, 25 kA IEC 60947-2.
