5SY4103-7 SIEMENS

The 5SY4103-7 is a miniature circuit breaker (MCB) manufactured by Siemens, designed for reliable overcurrent and short-circuit protection in electrical circuits. This MCB is a single-pole device, meaning it protects one electrical circuit. It has a C-curve tripping characteristic, making it suitable for circuits with moderate inrush currents, such as lighting and general-purpose circuits. The rated current for this MCB is 3A, indicating the maximum current it can continuously carry without tripping under normal operating conditions. It is designed for a rated voltage of 230/400V AC, commonly used in residential and commercial power distribution systems. The 5SY4103-7 has a breaking capacity of 10kA, meaning it can safely interrupt fault currents up to 10,000 amps. Its compact design, with a depth (D) of 70mm, allows for easy installation in distribution boards and consumer units. This MCB provides essential protection for electrical installations, preventing damage to equipment and reducing the risk of electrical fires. It conforms to relevant IEC standards, ensuring safety and performance.
