Product Description

Siemens 5SL5204-7RC MCB 4A 2-Pole C Characteristic 10kA DC

The Siemens 5SL5204-7RC is a SENTRON 5SL5 miniature circuit breaker (MCB) designed specifically for DC circuit protection. This Siemens DC MCB features a 4 A rated current, 2-pole configuration, C tripping characteristic, 440 V DC operating voltage and 10 kA short-circuit breaking capacity. It is designed to provide dependable protection against overload and short-circuit conditions in suitable DC electrical installations.

The Siemens 5SL5204-7RC 4A 2-pole DC MCB is suitable for applications where dedicated DC overcurrent protection is required. The Siemens 5SL5 DC range is intended for DC systems where fault interruption requires a protective device specifically suitable for DC operation. This makes the 5SL5204-7RC appropriate for compatible industrial DC distribution, automation panels, control circuits, battery systems, power electronics and other DC applications.

With a 4 A rated current, the 5SL5204-7RC is intended for appropriately designed low-current DC circuits. It can be considered for control circuits, auxiliary power circuits and suitable DC equipment where the connected load and conductor capacity are properly matched to the MCB rating.

The 2-pole configuration provides coordinated protection and switching for compatible DC circuits. Correct pole configuration and wiring are particularly important in DC applications because DC arc interruption differs from AC interruption. The applicable Siemens connection arrangement should therefore be followed for the intended DC voltage and installation.

The C tripping characteristic provides a defined response for suitable DC circuits where moderate starting or transient currents may occur. This makes the device suitable for selected control and equipment circuits where the connected load characteristics are compatible with a C-characteristic MCB.

The 10 kA short-circuit breaking capacity provides the specified fault-interruption capability for applicable DC protection arrangements. The prospective short-circuit current should always be evaluated before installation to ensure that the MCB is appropriately rated for the actual DC system.

Benefits

The Siemens 5SL5204-7RC provides dependable circuit protection for DC applications requiring a 4 A, 2-pole MCB with C characteristic and 10 kA breaking capacity. Its dedicated DC design makes it suitable for electrical systems where an appropriately rated DC protective device is required.

The 4 A rated current makes this MCB suitable for appropriately designed low-current DC circuits. Properly matching the MCB rating with the connected load and conductor capacity helps provide effective overload protection while supporting normal operating conditions.

The C tripping characteristic offers a practical solution for suitable DC circuits where moderate starting or transient currents may occur. It can be considered for selected industrial control circuits, automation systems, auxiliary supplies and compatible DC equipment, subject to correct circuit design.

The 2-pole construction provides coordinated protection and switching for compatible DC circuits. This makes the device suitable for integration into DC distribution boards, control panels, automation cabinets, battery systems and OEM electrical assemblies.

The 10 kA breaking capacity provides the specified short-circuit interruption capability for suitable DC installations. Because DC fault interruption depends on factors such as voltage, available fault current and circuit configuration, the actual system conditions should be verified before selecting the protective device.

The 440 V DC maximum operating voltage makes the 5SL5204-7RC suitable for compatible higher-voltage DC applications within its specified operating conditions. It can be considered for selected industrial DC distribution, control systems, battery-related circuits and power-electronics applications.
