Product Description

Siemens 5SL5225-7RC MCB 25A 2-Pole C Characteristic 10kA DC

The Siemens 5SL5225-7RC is a SENTRON 5SL5 miniature circuit breaker (MCB) designed specifically for DC circuit protection. This Siemens DC MCB features a 25 A rated current, 2-pole configuration, C tripping characteristic, 440 V DC operating voltage and 10 kA short-circuit breaking capacity. It is intended for electrical systems where dependable protection against overload and short-circuit conditions is required in DC applications.

The Siemens 5SL5225-7RC 25A 2-pole DC MCB is suitable for appropriately designed DC distribution and control circuits. Unlike a conventional AC-only miniature circuit breaker, the Siemens 5SL5 DC range is designed for the specific requirements of DC fault interruption, making it suitable for selected industrial DC systems, control circuits, battery applications, power electronics and other compatible DC installations.

The 2-pole configuration provides coordinated protection and switching for compatible DC circuits. This makes the device suitable for electrical panels where two poles need to be protected or switched according to the system design. Correct pole arrangement and wiring are especially important in DC applications because DC fault arcs do not naturally extinguish at a zero crossing as they do in AC systems.

With a 25 A rated current, the 5SL5225-7RC is suitable for medium-current DC circuits where the connected load, conductor capacity and protection requirements match the MCB rating. Proper coordination with upstream and downstream protective equipment is essential for reliable operation.

The C tripping characteristic provides a defined response for suitable circuits with moderate starting or transient currents. It can be considered for compatible DC loads where the expected operating and startup current profile is appropriate for the selected characteristic.

The 10 kA short-circuit breaking capacity provides the specified fault-interruption capability for applicable DC protection arrangements. Before installation, the prospective short-circuit current should be assessed to ensure the MCB is suitable for the actual fault level.

Benefits

The Siemens 5SL5225-7RC provides dependable circuit protection for DC applications requiring a 25 A, 2-pole MCB with C characteristic and 10 kA breaking capacity. Its dedicated DC design makes it suitable for applications where the interruption requirements are different from conventional AC circuit protection.

The 25 A rated current makes this MCB appropriate for suitably designed medium-current DC circuits. Correct selection of the protective-device rating helps ensure that cables, conductors and connected equipment are protected against excessive current while allowing normal operating current to flow without unwanted tripping.

The C tripping characteristic provides a practical option for compatible DC circuits where moderate starting or transient currents may occur. This can make the device suitable for selected control systems, DC equipment and industrial applications where the load characteristics match the selected tripping curve.

The 2-pole configuration provides coordinated protection and switching for compatible DC circuits. It can help panel builders create an organized protection arrangement in DC distribution boards, control panels, battery systems and OEM electrical assemblies.

The 10 kA breaking capacity provides a high specified short-circuit interruption capability for suitable DC installations. Since actual DC fault interruption depends on system voltage, wiring configuration and available fault current, the complete installation should be evaluated before selection.

The 440 V DC maximum operating voltage makes the 5SL5225-7RC suitable for selected higher-voltage DC applications within its specified operating conditions. This can include industrial DC distribution, energy systems, power electronics and other compatible applications.

The Siemens SENTRON 5SL5 DC series provides a dedicated modular solution for professional DC circuit protection. This makes the 5SL5225-7RC relevant for OEMs, panel builders, electrical contractors, automation integrators, battery-system designers and industrial maintenance teams.
