5SY6103-8 SIEMENS

The 5SY6103-8 is a miniature circuit breaker (MCB) designed and manufactured by Siemens. It is a single-pole (1P) circuit breaker, meaning it protects a single electrical circuit. This MCB is rated for a voltage of 230/400V, making it suitable for standard residential and commercial power systems. It has a breaking capacity of 6kA, indicating its ability to safely interrupt fault currents up to 6,000 Amperes. The tripping characteristic of this MCB is D-curve, which means it is designed to handle high inrush currents, making it suitable for inductive loads like motors and transformers. The rated current of the 5SY6103-8 is 3A, protecting circuits with a maximum current draw of 3 Amperes. The device has a depth of 70mm. It provides reliable overcurrent and short-circuit protection for electrical circuits. This MCB is commonly used in distribution boards and control panels to protect electrical equipment and prevent damage from electrical faults. It conforms to IEC standards for safety and performance.
