Siemens 5SL4140-7RC MCB 40A 1-Pole C Characteristic 10kA

The Siemens 5SL4140-7RC is a SENTRON 5SL4 miniature circuit breaker (MCB) designed to provide dependable protection against overload and short-circuit conditions in suitable electrical installations. This MCB features a 40 A rated current, 1-pole configuration, C tripping characteristic, 240/415 V AC rated voltage and 10 kA short-circuit breaking capacity, making it suitable for appropriately designed industrial, commercial and electrical distribution applications.

The Siemens 5SL4140-7RC 40A 1-pole MCB is designed for individual electrical circuits where reliable 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 device suitable for selected distribution, control, machinery and electrical equipment protection applications.

The 1-pole configuration provides a compact solution for individual circuit protection and 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 40 A rated current, the 5SL4140-7RC is suitable for appropriately designed medium-to-high 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 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 evaluated before selecting the MCB to confirm that its breaking capacity is adequate for the electrical system.

The 240/415 V AC rating supports use in compatible AC electrical systems. As part of the Siemens SENTRON 5SL4 series, the 5SL4140-7RC provides a compact modular circuit protection solution for professional electrical installations.
