Siemens 5SY4663-7 Miniature circuit breaker

Its C-curve trip profile allows it to handle inductive loads such as large motors and pumps that generate high inrush currents during startup, while still offering fast disconnection in overload or short-circuit conditions. The 3+N-pole design ensures that all live wires, including the neutral, are simultaneously disconnected in the event of a fault, thereby preventing voltage imbalances and protecting connected equipment.

The 5SY4663-7 is ideal for use in factory distribution systems, industrial machinery control panels, and commercial electrical installations where high current capacity and reliable circuit protection are essential. It complies with IEC standards and provides long-term mechanical and electrical durability, making it a reliable solution for enhancing safety, efficiency, and reliability in advanced electrical systems.
