Siemens 5SL6125-6RC MCB 25A 1-Pole B Characteristic 7.5kA

The Siemens 5SL6125-6RC is a SENTRON 5SL6 miniature circuit breaker (MCB) designed to provide dependable protection against overload and short-circuit conditions in suitable electrical installations. This Siemens MCB features a 25 A rated current, 1-pole configuration, B tripping characteristic and 7.5 kA short-circuit breaking capacity, making it suitable for appropriately designed electrical distribution, control and equipment protection applications.

The Siemens 5SL6125-6RC 25A 1-pole MCB is designed for individual circuits where compact and reliable overcurrent protection is required. Its B tripping characteristic is generally suitable for electrical circuits with comparatively low starting or inrush currents. This makes it a practical choice for selected general-purpose distribution circuits, resistive loads, control circuits and other compatible electrical applications.

The 1-pole configuration provides a space-efficient circuit protection solution for individual circuits. It can be integrated into electrical distribution boards, industrial control panels, automation cabinets, machinery panels and OEM electrical assemblies where dedicated circuit protection is required.

With a 25 A rated current, the 5SL6125-6RC is suitable for appropriately designed medium-current individual circuits. Proper coordination between the MCB rating, connected load, conductor capacity and upstream and downstream protective devices is essential for safe and reliable electrical operation.

The 7.5 kA short-circuit breaking capacity provides the specified capability to interrupt suitable short-circuit fault currents within the applicable ratings of the device. The prospective short-circuit current at the installation point should always be assessed before selecting the MCB to ensure adequate fault protection.

As part of the Siemens SENTRON 5SL6 series, the 5SL6125-6RC provides a compact modular solution for professional circuit protection. It can be considered by panel builders, OEMs, electrical contractors, system integrators and industrial maintenance teams looking for Siemens MCBs for industrial and commercial electrical applications.

Benefits

The Siemens 5SL6125-6RC provides dependable circuit protection for applications requiring a 25 A, 1-pole MCB with B characteristic and 7.5 kA breaking capacity. Its compact 1-pole design is suitable for protecting individual circuits while helping maintain an organized and space-efficient electrical panel layout.

The B tripping characteristic is generally selected for circuits where the expected starting or inrush current is relatively low. This makes the MCB suitable for appropriately designed general distribution, resistive-load, control and auxiliary circuits where the B curve matches the connected equipment.

The 7.5 kA breaking capacity provides the specified fault-interruption capability for suitable installations. Proper assessment of the prospective short-circuit current is important to confirm that the MCB is adequately rated for the electrical system.

The 1-pole configuration provides an efficient solution for individual circuit protection in distribution boards, industrial control cabinets, automation panels, machinery and OEM electrical assemblies. Its modular format can help panel builders optimize available space while maintaining a structured protection arrangement.

The 25 A rated current makes the 5SL6125-6RC suitable for appropriately designed medium-current individual circuits. Correct coordination between the protective device, cable capacity and connected load is essential to provide effective overcurrent protection.

The B characteristic is particularly suitable for loads with relatively low inrush current. For equipment with significantly higher starting currents, such as certain motors or transformers, another tripping characteristic may be more appropriate based on the actual application.

As part of the Siemens SENTRON 5SL6 family, the 5SL6125-6RC provides a professional modular circuit protection solution for industrial, commercial, OEM, automation and electrical distribution applications.
