The Siemens 5SY4225-7 is a robust miniature circuit breaker designed to provide reliable overcurrent protection in a variety of applications. Engineered for quick assembly, this two-pole circuit breaker is suitable for both AC and DC operations, with a rated voltage of 400V and a rated current of 25A. It features a C tripping characteristic, ensuring a precise response to overcurrent conditions, making it an ideal choice for industrial and commercial electrical systems.
With a compact width of 36mm and a depth of 76mm, the 5SY4225-7 is designed to save space in electrical enclosures, while its modular design allows for easy installation and maintenance. The breaker is capable of withstanding ambient temperatures ranging from -25°C to +55°C during operation, and -40°C to +75°C during storage, ensuring consistent performance in diverse environmental conditions.
The device boasts a high switching capacity current, with ratings of 20kA according to IEC 60947-2 for AC and 15kA for DC, as well as a 10kA breaking capacity short-circuit current according to EN 60898. This ensures reliable protection for electrical circuits against short-circuit conditions.
Additional features include touch-protection, a sealable design for security, and compliance with overvoltage class 3 and pollution degree 3 standards. The 5SY4225-7 also meets the requirements for main switches in accordance with EN 60204-1, highlighting its suitability for integration into machinery safety systems.
The circuit breaker's terminals are designed to accommodate a wide range of conductor sizes, from 0.75mm² up to 35mm² for solid and stranded wires, and up to 25mm² for finely stranded wires with wire end processing. This flexibility ensures compatibility with various wiring configurations, simplifying installation processes.
Overall, the Siemens 5SY4225-7 miniature circuit breaker is a dependable and efficient solution for safeguarding electrical circuits against overloads and short circuits, making it a valuable component in ensuring the safety and reliability of electrical installations.
