5SY4408-8 SIEMENS

The 5SY4408-8 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 D-curve tripping characteristic, making it suitable for circuits with high inrush currents, such as those found in inductive loads like motors and transformers. With a rated current of 8A, it can handle moderate electrical loads. The 5SY4408-8 is designed for a maximum voltage of 400V AC and has a short-circuit breaking capacity of 10kA, ensuring it can safely interrupt fault currents. Its compact design, with a depth of 70mm, allows for easy installation in distribution boards and control panels. This MCB provides overload and short-circuit protection, preventing damage to equipment and reducing the risk of electrical fires. It complies with relevant IEC standards, ensuring safety and performance. The Siemens 5SY4408-8 is a reliable choice for protecting electrical circuits in residential, commercial, and industrial settings.
