5SY4303-5 SIEMENS

The 5SY4303-5 is a miniature circuit breaker (MCB) designed and manufactured by Siemens. It is engineered to provide reliable protection against overcurrents and short circuits in electrical circuits. This three-pole MCB is suitable for use in systems with a voltage rating of up to 400V. It has a breaking capacity of 10kA, indicating its ability to safely interrupt high fault currents. The device features an A-characteristic tripping curve, making it ideal for protecting circuits with sensitive electronic components. With a rated current of 3A, it is designed for applications with relatively low current demands. The compact design, with a depth (D) of 70mm, allows for easy installation in distribution boards and control panels. This MCB ensures the safety and reliability of electrical installations by quickly disconnecting the circuit in the event of an overload or short circuit, preventing damage to equipment and reducing the risk of electrical hazards. It adheres to industry standards for performance and safety.
