Siemens 5SY6306-7CC — SENTRON 6A C-Curve MCB, 3-Pole
The Siemens 5SY6306-7CC is a SENTRON miniature circuit breaker rated 6 A at 35 °C with a C tripping characteristic, 3 poles, and a 6 kA breaking capacity per EN 60898.
Rated 6 A at 35 °C, the 5SY6306-7CC derates to 5.51 A at 40 °C, 5.25 A at 45 °C, 4.97 A at 50 °C, and 4.69 A at 55 °C. In a warm panel — say 50 °C ambient — you lose about 17% of the nominal rating. Plan the branch circuit load accordingly; the 6 A label is only valid at the reference temperature.
Physical Integration
Dimensions: 54 mm wide (3 MW), 90 mm high, 76 mm deep, with an installation depth of 70 mm. The quick-assembly fastening method snaps onto a DIN rail. Halogen-free and silicon-free construction meets clean-room and high-reliability requirements.
Energy limitation class 3. Functional designation F per EN 61346-2 and IEC 81346-2. Suitable for mechanical engineering and industrial applications per the manufacturer's specification. No neutral conductor switching — this is a 3-pole breaker for line-side protection only.
