Product Description

Siemens 5SL4240-7RC MCB 40A 2-Pole C Characteristic 10kA

The Siemens 5SL4240-7RC 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 40 A rated current, 2-pole configuration, C tripping characteristic, 415 V rated voltage and 10 kA short-circuit breaking capacity, making it suitable for appropriately designed industrial, commercial and electrical distribution applications.

The Siemens 5SL4240-7RC 40A 2-pole MCB is designed for circuits requiring dependable overcurrent protection with coordinated protection and switching across two poles. Its C tripping characteristic is generally suitable for general-purpose electrical circuits where moderate starting or inrush currents may occur. This makes the device suitable for selected distribution, control, machinery, automation and electrical equipment protection applications.

The 2-pole configuration provides coordinated protection and switching for compatible two-pole electrical circuits. It can be integrated into electrical distribution boards, industrial control panels, commercial electrical panels, machinery control systems, automation cabinets and OEM electrical assemblies where two-pole circuit protection is required.

With a 40 A rated current, the 5SL4240-7RC is suitable for appropriately designed medium-to-high current 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 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 ensure that its breaking capacity is appropriate for the electrical system.

The C tripping characteristic makes this MCB suitable for many general-purpose electrical loads where moderate starting or inrush currents may occur. Correct selection should be based on the connected equipment, load profile and overall protection design.

As part of the Siemens SENTRON 5SL4 series, the 5SL4240-7RC provides a compact modular circuit protection solution for professional electrical installations. It can be considered by panel builders, OEMs, electrical contractors, system integrators and industrial maintenance teams.
