The Siemens 5SY4102-7 is a single-pole miniature circuit breaker designed for reliable overcurrent protection in electrical systems. It operates with a C-type tripping characteristic, suitable for applications requiring higher inrush currents.
This circuit breaker has a rated voltage of 400V AC and a rated current of 2A at 35°C, with derated values at higher temperatures. Its switching capacity is 10kA according to EN 60898 and up to 35kA according to IEC 60947-2, ensuring robust protection against short circuits.
Designed for easy installation, the 5SY4102-7 features DIN rail mounting and screw-type terminals that accept solid or stranded conductors from 0.75mm² to 35mm². It has a mechanical service life of 10,000 switching cycles and meets overvoltage category III and degree of pollution 3 standards.
Additional features include halogen-free construction and suitability for supplementary devices, making it a versatile component for industrial and mechanical engineering applications.
The rated current is 2A at 35°C ambient temperature. At higher temperatures, the current is derated: 1.9A at 40°C, 1.85A at 45°C, 1.8A at 50°C, 1.75A at 55°C, and 1.7A at 60°C.
C-curve, suitable for moderate inrush currents.
The switching capacity varies by standard: 10kA according to EN 60898, 35kA according to IEC 60947-2, and 15kA at DC.
