5SY4105-7 SIEMENS

The 5SY4105-7 is a miniature circuit breaker (MCB) manufactured by Siemens, designed for reliable overcurrent and short-circuit protection in electrical circuits. This 1-pole MCB is suitable for use in residential, commercial, and industrial applications. It has a C-curve tripping characteristic, which means it trips relatively quickly for moderate overloads and faster for high short-circuit currents. The rated current for this MCB is 0.5A, making it suitable for protecting sensitive electronic equipment and lighting circuits. It is designed for systems with a rated voltage of 230/400V AC and has a high breaking capacity of 10kA, ensuring it can safely interrupt high fault currents. The device has a compact design with a depth (D) of 70mm, allowing for easy installation in distribution boards and consumer units. This MCB provides reliable protection against overload and short circuits, enhancing the safety and reliability of electrical installations. It helps to prevent damage to equipment and reduces the risk of electrical fires. Siemens MCBs are known for their quality and compliance with international standards.
