The Siemens 5SY4110-7-ZW07 is a 1-pole SENTRON miniature circuit breaker with a C tripping characteristic, rated 10 kA per EN 60898-1 and 20 kA per IEC 60947-2. The C curve means it tolerates moderate inrush — typical for motor-starter or lighting circuits — before tripping on short-circuit. Per the datasheet, it also carries a DC rating of 15 kA at 60 V (IEC 60947-2) and a UL 1077 interrupting capacity of 5 kA, so it can serve panels built to North American or IEC standards.
Rated for ambient temperatures from -40 °C to 75 °C, with derating above 55 °C per the humidity table (max 95% RH at 55 °C, dropping to 35% at 75 °C). Degree of pollution 3, overvoltage category III. Mounting position any; fastens via the quick-assembly system onto a DIN rail.
