The Siemens 5SL7240-7RC is a SENTRON 5SL7 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 AC rated voltage and 15 kA short-circuit breaking capacity. Product documentation and current product references confirm the 2-pole, 40 A, C-characteristic and 15 kA configuration.
The Siemens 5SL7240-7RC 40A 2-pole MCB is designed for electrical circuits where dependable overcurrent protection is required with a C tripping characteristic. The C curve is generally suitable for general-purpose circuits where moderate starting or inrush currents can occur.
With its 2-pole configuration, the MCB can provide coordinated protection and switching for compatible two-pole circuits. It can be used in suitable distribution boards, control panels, machinery panels, commercial electrical installations and OEM electrical assemblies.
The 15 kA short-circuit breaking capacity provides a high specified fault-interruption capability for suitable installations. The product is identified with a 15 kA breaking capacity and C curve.
The 40 A rated current makes this MCB suitable for appropriately designed higher-current circuits. The protective-device rating should always be coordinated with the connected load, conductor capacity, installation conditions and upstream/downstream protection.
The 415 V AC rating supports use in compatible electrical distribution systems. Product information identifies the 5SL7240-7RC as a 415 V, 2-pole, 40 A C-curve MCB.
As part of the Siemens SENTRON 5SL7 series, the 5SL7240-7RC is suitable for professional electrical protection applications and can be considered by panel builders, OEMs, electrical contractors, system integrators and industrial maintenance teams.
The Siemens 5SL7240-7RC 40A 2-pole C curve MCB can be considered for:
The Siemens 5SL7240-7RC provides dependable circuit protection for applications requiring a 40 A, 2-pole MCB with C characteristic and 15 kA breaking capacity. Its C tripping characteristic makes it a practical choice for many general-purpose circuits where moderate starting or inrush currents can occur.
The C curve can be suitable for a wide range of distribution and equipment circuits where the expected startup current is higher than normal operating current but does not require a D-characteristic protective device. Proper curve selection helps ensure reliable protection while avoiding unnecessary nuisance tripping during normal equipment operation.
The 15 kA breaking capacity provides a high specified short-circuit interruption capability for suitable electrical installations. Before installation, the prospective short-circuit current of the circuit should be checked to ensure that the MCB's breaking capacity is appropriate for the application.
The 2-pole construction provides coordinated protection and switching for compatible two-pole circuits. This makes the device suitable for distribution boards, electrical control cabinets, machinery panels and OEM electrical assemblies.
With a 40 A rated current, the 5SL7240-7RC can be used for suitably designed higher-current circuits. Correct coordination between the MCB, connected load and conductor capacity is essential for safe and reliable operation.
The 415 V AC rating supports use in compatible electrical distribution systems and makes this MCB suitable for various industrial and commercial panel applications. Current product information identifies the device as a 40 A, 2P, C-curve, 15 kA MCB with 415 V rated operational voltage.
The Siemens SENTRON 5SL7 series provides a practical solution for professional electrical protection requirements. The 5SL7240-7RC can therefore be considered for panel builders, OEMs, electrical contractors, system integrators and industrial maintenance applications.
