5SY4204-5 SIEMENS

The 5SY4204-5 is a miniature circuit breaker (MCB) manufactured by Siemens, designed for reliable circuit protection in residential, commercial, and industrial applications. This 2-pole MCB offers a breaking capacity of 10kA at 400V AC, ensuring effective interruption of short-circuit currents to prevent damage to equipment and wiring. With a current rating of 4A, it is suitable for protecting circuits with relatively low current demands. The A-characteristic tripping curve provides fast tripping for short circuits while avoiding nuisance tripping due to transient overloads. Its compact design, with a depth of 70mm, allows for space-saving installation in distribution boards and consumer units. The 5SY4204-5 MCB incorporates features such as thermal-magnetic trip mechanisms for overload and short-circuit protection. It also includes a trip-free mechanism, ensuring that the breaker trips even when the handle is held in the ON position during a fault. The clear contact position indicator provides visual confirmation of the breaker's status, enhancing safety and ease of maintenance. This MCB is designed and tested to meet relevant IEC standards, guaranteeing its performance and reliability. It offers a dependable solution for safeguarding electrical circuits and equipment against overcurrents and short circuits.
