5SY6103-7 SIEMENS

The 5SY6103-7 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 AC and has a breaking capacity of 6kA, indicating its ability to safely interrupt fault currents up to 6000 Amperes. The tripping characteristic is C-curve, which means it trips faster than a B-curve but slower than a D-curve, making it suitable for general applications with moderate inrush currents. The rated current for this MCB is 3A, suitable for protecting circuits with low current demands. Its depth is 70mm. Miniature circuit breakers like the 5SY6103-7 are essential components in electrical distribution boards, providing protection against overloads and short circuits. They are designed to automatically switch off the electrical circuit during an abnormal condition, preventing damage to equipment and reducing the risk of electrical fires. This MCB is suitable for residential, commercial, and industrial applications. It offers reliable and efficient protection for electrical circuits.
