The Siemens 5SL6120-7RC is a SENTRON 5SL6 miniature circuit breaker (MCB) designed to provide reliable protection against overload and short-circuit conditions in suitable electrical installations. This Siemens MCB features a 20 A rated current, 1-pole configuration, C 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 5SL6120-7RC 20A 1-pole MCB is designed for individual electrical circuits where dependable overcurrent protection is required in a compact modular format. Its C tripping characteristic is generally suitable for general-purpose circuits where moderate starting or inrush currents may occur. This makes the MCB a practical choice for distribution circuits, control applications, auxiliary circuits and compatible electrical equipment.
The 1-pole configuration provides a space-efficient solution for individual circuit protection. It can be integrated into electrical distribution boards, industrial control panels, automation cabinets, machinery panels and OEM electrical assemblies where dedicated overcurrent protection is required for individual circuits.
With a 20 A rated current, the 5SL6120-7RC is suitable for appropriately designed low-to-medium current circuits. Proper coordination between the MCB rating, connected load, conductor capacity and upstream and downstream protective devices is important for safe and reliable electrical operation.
The 7.5 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 evaluated to confirm that the selected MCB provides adequate short-circuit protection for the electrical system.
As part of the Siemens SENTRON 5SL6 series, the 5SL6120-7RC provides a compact and professional circuit protection solution. It can be considered by panel builders, OEMs, electrical contractors, system integrators, automation professionals and industrial maintenance teams looking for Siemens MCBs for suitable electrical applications.
The Siemens 5SL6120-7RC 20A 1-pole C curve MCB can be considered for:
The Siemens 5SL6120-7RC provides dependable circuit protection for applications requiring a 20 A, 1-pole MCB with C characteristic and 7.5 kA breaking capacity. Its compact 1-pole design makes it suitable for protecting individual circuits while helping maintain an organized and space-efficient electrical panel layout.
The C tripping characteristic makes the MCB suitable for many general-purpose electrical circuits where moderate starting or inrush currents may occur. It can therefore be considered for appropriately designed distribution, control, auxiliary and equipment circuits where the connected load characteristics match a C-curve protective device.
The 7.5 kA breaking capacity provides the specified capability to interrupt suitable short-circuit fault currents within the applicable ratings of the device. This helps provide dependable protection against fault conditions when the MCB is correctly selected and coordinated with the rest of the electrical protection system.
The 1-pole construction offers a compact solution for individual circuit protection. This can be particularly useful in electrical distribution boards, automation panels, control cabinets, machinery systems and OEM electrical assemblies where multiple individual circuits require dedicated circuit breakers.
The 20 A rated current makes the 5SL6120-7RC suitable for appropriately designed low-to-medium current circuits. Correct coordination between the protective-device rating, conductor capacity and connected load is essential for effective overcurrent protection.
The C characteristic provides a versatile option for electrical circuits with moderate inrush currents. For equipment that generates significantly higher starting currents, such as certain motors or transformers, another tripping characteristic may be more suitable depending on the application.
The Siemens SENTRON 5SL6 series provides a practical modular circuit protection solution for industrial and commercial electrical systems. The 5SL6120-7RC can be considered for OEM panels, industrial automation systems, machinery control applications, electrical distribution boards and commercial electrical installations.
