The Siemens 5SP4291-7RC is a SENTRON 5SP4 miniature circuit breaker (MCB) designed to provide dependable protection against overload and short-circuit conditions in electrical installations. This Siemens MCB features a 125 A rated current, 2-pole configuration, C tripping characteristic and 10 kA short-circuit breaking capacity, making it suitable for higher-current electrical distribution and protection applications.
The Siemens 5SP4291-7RC 125A 2-pole MCB is designed for electrical circuits where reliable overcurrent protection and two-pole switching are required. Its C characteristic is commonly selected for general-purpose electrical circuits where connected loads can produce moderate starting or inrush currents. This makes it suitable for appropriately designed industrial, commercial and distribution applications.
With its 2-pole configuration, the 5SP4291-7RC provides simultaneous switching and protection across two poles as required by the electrical system design. It can be considered for suitable distribution arrangements where a higher-current two-pole protective device is required.
The 10 kA short-circuit breaking capacity allows the MCB to interrupt specified short-circuit fault currents within its applicable ratings. This helps protect electrical cables, equipment and downstream circuits against the effects of overload and short-circuit conditions.
As part of the Siemens SENTRON 5SP4 series, the 5SP4291-7RC is suitable for professional electrical distribution systems, industrial control panels, commercial installations, OEM equipment and infrastructure projects. The product family is designed for modular panel integration and can be combined with compatible Siemens accessories where additional signalling or monitoring functions are required.
The 125 A Siemens 2-pole MCB can be considered where the electrical load and installation design require higher-current circuit protection. Correct selection should always take into account the load current, conductor capacity, prospective short-circuit current, ambient temperature and coordination with upstream and downstream protective devices.
The Siemens 5SP4291-7RC 125A 2-pole C curve MCB can be used in:
The Siemens 5SP4291-7RC provides dependable circuit protection for systems requiring a 125 A, 2-pole MCB with C characteristic. Its C tripping characteristic can be suitable for general electrical circuits where moderate inrush currents occur, subject to correct system design.
The 10 kA breaking capacity provides protection against specified short-circuit fault levels. When correctly selected and coordinated, the MCB can help protect electrical wiring and connected equipment from damage caused by overload and short-circuit conditions.
The 2-pole design provides a compact solution for electrical systems requiring two-pole protection and switching. It can help panel builders maintain an organized and efficient layout while providing the required circuit protection.
Being part of the Siemens SENTRON 5SP4 family, the 5SP4291-7RC is suitable for professional electrical distribution applications and can be used with compatible accessories where auxiliary signalling, status indication or monitoring functions are required.
