The Siemens 5SL4225-0RC is a SENTRON 5SL4 miniature circuit breaker (MCB) designed to provide reliable protection against overload and short-circuit conditions in suitable electrical installations. This MCB features a 25 A rated current, 2-pole configuration, Z tripping characteristic and 10 kA short-circuit breaking capacity, making it suitable for appropriately designed industrial, commercial and electrical protection applications.
The Siemens 5SL4225-0RC 25A 2-pole MCB is designed for circuits where a Z tripping characteristic is required. A Z characteristic is generally selected for applications requiring a more sensitive response to overcurrent conditions than typical B- or C-characteristic devices. This can make the device suitable for selected electronic equipment, control circuits and sensitive electrical loads, subject to correct application.
The 2-pole configuration provides coordinated protection and switching for compatible two-pole electrical circuits. The MCB can be integrated into electrical distribution boards, industrial control panels, automation cabinets, machinery panels and OEM electrical assemblies where two-pole circuit protection is required.
With a 25 A rated current, the 5SL4225-0RC is suitable for appropriately designed medium-current circuits. Proper coordination between the MCB rating, connected load, conductor capacity and upstream and downstream protective devices is essential for safe and reliable operation.
The 10 kA short-circuit breaking capacity provides the specified fault-interruption capability for suitable installations. The prospective short-circuit current at the installation point should always be assessed before selecting the MCB to confirm that the device is appropriately rated for the electrical system.
The Z tripping characteristic can be useful for selected control and electronic applications where relatively sensitive overcurrent protection is required. The exact characteristic should always be matched to the connected equipment to avoid unwanted tripping during normal operating or startup conditions.
As part of the Siemens SENTRON 5SL4 series, the 5SL4225-0RC provides a compact modular circuit protection solution for professional electrical installations. It can be considered by panel builders, OEMs, electrical contractors, system integrators, automation professionals and industrial maintenance teams.
The Siemens 5SL4225-0RC 25A 2-pole Z curve MCB can be considered for:
The Siemens 5SL4225-0RC provides dependable circuit protection for applications requiring a 25 A, 2-pole MCB with Z characteristic and 10 kA breaking capacity. Its Z tripping characteristic makes it suitable for selected applications where a comparatively sensitive response to overcurrent conditions is required.
The Z characteristic can be useful for certain electronic and control circuits where rapid response to relatively lower overcurrent levels is desirable. Because this characteristic is more sensitive than standard general-purpose curves, it should be carefully matched with the connected equipment and the expected operating current.
The 2-pole construction provides coordinated protection and switching for compatible two-pole circuits. This makes the MCB suitable for electrical distribution boards, industrial control cabinets, automation panels, machinery systems and OEM electrical assemblies where two-pole protection is required.
The 25 A rated current makes the 5SL4225-0RC suitable for appropriately designed medium-current circuits. Correct coordination between the protective-device rating, conductor capacity, connected load and other protective devices is important for reliable circuit protection.
The 10 kA breaking capacity provides the specified capability to interrupt suitable short-circuit fault currents within the applicable device ratings. The prospective short-circuit current should always be assessed to confirm that the MCB is suitable for the intended installation.
The compact Siemens SENTRON 5SL4 design supports organized installation in professional electrical panels and distribution assemblies. The 5SL4225-0RC can be considered for industrial automation, electronic equipment, OEM machinery, control systems and electrical distribution applications.
