5SY4408-7 SIEMENS

The 5SY4408-7 is a miniature circuit breaker (MCB) manufactured by Siemens, designed for reliable circuit protection in various applications. It is a 4-pole breaker, meaning it can interrupt current flow in four separate circuits simultaneously. This MCB has a C-curve tripping characteristic, making it suitable for circuits with moderate inrush currents, such as those found in lighting and general-purpose applications. With a rated current of 8A, it can handle continuous loads up to 8 amperes without tripping. The 5SY4408-7 is designed for a maximum operating voltage of 400V AC. It boasts a high breaking capacity of 10kA, ensuring it can safely interrupt high fault currents, preventing damage to equipment and minimizing the risk of electrical hazards. Its compact design, with a depth (D) of 70mm, allows for easy installation in distribution boards and control panels where space is limited. This MCB provides reliable overload and short-circuit protection, contributing to the safety and longevity of electrical systems. Siemens is a trusted brand known for its high-quality electrical components, ensuring the 5SY4408-7 meets stringent industry standards.
