The Siemens 5SY4125-7 is a robust miniature circuit breaker designed to provide reliable overcurrent protection for electrical circuits. Engineered for both AC and DC applications, this MCB operates at a rated voltage of 400 V and has a notable interrupt rate of 10 kA, ensuring effective disconnection in the event of a fault. Its compact dimensions of 90 x 18 x 76 mm allow for efficient use of space within electrical installations. This circuit breaker is a single-pole device, characterised by a C tripping curve, making it suitable for protecting installations with a moderate inrush current, such as small motors and lighting circuits. The 5SY4125-7 is designed for quick assembly, with a mounting depth of 70 mm, and can be installed in any position, providing flexibility in various applications. Constructed with safety and durability in mind, the 5SY4125-7 features touch protection and is sealable to prevent tampering. It is also halogen-free and silicon-free, minimising environmental impact and ensuring compliance with industry standards for material safety. The MCB's mechanical life is rated for 20,000 operating cycles, indicating a long-lasting and reliable performance for mechanical engineering and industrial environments. With its ability to handle a rated current of 25 A and its compliance with overvoltage category III, the Siemens 5SY4125-7 is an essential component for safeguarding electrical systems against overcurrent conditions.
