5SY4250-7 SIEMENS

The 5SY4250-7 is a miniature circuit breaker (MCB) designed and manufactured by Siemens, a global leader in electrical engineering and electronics. This particular MCB is a 2-pole device, meaning it protects two separate circuits simultaneously, making it suitable for applications requiring double-pole protection. It has a C-curve tripping characteristic, which indicates its sensitivity to overloads and short circuits, providing a balance between protection and preventing nuisance tripping. The MCB is rated for a current of 50 Amperes, making it suitable for circuits with moderate to high current demands. It is designed to operate at a voltage of up to 400V AC, which is standard for many residential, commercial, and industrial applications. The 5SY4250-7 has a high breaking capacity of 10kA, meaning it can safely interrupt fault currents up to 10,000 Amperes, ensuring reliable protection against short circuits. Its compact design, with a depth (D) of 70mm, allows for easy installation in standard distribution boards and consumer units. This MCB provides reliable protection against overloads and short circuits in electrical circuits. It is suitable for a wide range of applications, including residential, commercial, and industrial settings. The 5SY4250-7 is a reliable and essential component for ensuring the safety and integrity of electrical installations.
