5SY4650-7 SIEMENS

The 5SY4650-7 is a miniature circuit breaker (MCB) manufactured by Siemens, designed for reliable circuit protection in residential, commercial, and industrial applications. This MCB is a 3+N-pole device, meaning it has three poles for phase conductors and one pole for the neutral conductor. It has a C-curve tripping characteristic, which provides a balance between sensitivity and immunity to nuisance tripping, making it suitable for general-purpose circuits with moderate inrush currents. The 5SY4650-7 has a rated current of 50A, indicating its capacity to handle continuous loads up to 50 amperes. It is designed for a rated voltage of 400V AC, which is standard for many electrical systems. With a breaking capacity of 10kA, this MCB can safely interrupt fault currents up to 10,000 amperes, protecting downstream equipment and preventing electrical hazards. The device has a depth (D) of 70mm. This MCB provides reliable protection against overloads and short circuits, ensuring the safety and longevity of electrical installations. Siemens MCBs are known for their quality, durability, and compliance with international standards.
