Product Description

Siemens 5SL5202-7RC MCB 2A 2-Pole C Characteristic 10kA DC

The Siemens 5SL5202-7RC is a SENTRON 5SL5 miniature circuit breaker (MCB) designed specifically for DC circuit protection. This model features a 2 A rated current, 2-pole configuration, C tripping characteristic, 440 V DC operating voltage and 10 kA short-circuit breaking capacity, making it suitable for appropriately designed low-current DC electrical installations.

The Siemens 5SL5202-7RC 2A 2-pole DC MCB is designed to protect compatible DC circuits against overload and short-circuit conditions. Because DC fault interruption has different characteristics from AC fault interruption, a DC-rated protective device is required for applications where the circuit operates within the specified DC voltage and fault-current ratings.

With a 2 A rated current, this MCB is suitable for low-current DC circuits where the connected load and conductor capacity are correctly matched with the protective device. It can be considered for selected control circuits, auxiliary supplies, automation systems, signalling circuits and compatible industrial DC equipment.

The 2-pole configuration provides coordinated protection and switching for compatible DC circuits. Proper pole connection and wiring are especially important in DC systems, so the applicable Siemens connection arrangement should be followed for the intended operating voltage and application.

The C tripping characteristic provides a suitable response for compatible circuits where moderate starting or transient currents may occur. Correct characteristic selection should always be based on the actual load profile and the complete electrical protection design.

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 assessed before installation to verify that the MCB is suitable for the actual DC system.

Benefits

The Siemens 5SL5202-7RC provides dependable circuit protection for DC applications requiring a 2 A, 2-pole MCB with C characteristic and 10 kA breaking capacity. Its dedicated DC design makes it suitable for applications where the protective device must be rated for DC fault interruption.

The 2 A current rating makes this MCB appropriate for suitably designed low-current DC circuits. Correctly matching the MCB with the connected load and conductor capacity helps provide effective overload protection while allowing the circuit to operate under normal conditions.

The C tripping characteristic provides a practical solution for compatible DC circuits where moderate starting or transient currents may occur. This can make the device suitable for selected control, automation, auxiliary and equipment circuits where the load characteristics match a C-curve protective device.

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

The 10 kA breaking capacity provides the specified capability to interrupt suitable short-circuit fault currents. In DC applications, the actual breaking performance depends on the system voltage, available fault current and connection arrangement, so these parameters should be verified during protection design.

The 440 V DC operating voltage makes the 5SL5202-7RC suitable for compatible higher-voltage DC applications within its specified rating. It can therefore be considered for selected industrial DC distribution, control and power-electronics applications.

The Siemens SENTRON 5SL5 DC series provides a dedicated modular circuit protection solution for professional electrical applications. The 5SL5202-7RC can be considered by OEMs, panel builders, electrical contractors, automation integrators and industrial maintenance teams.
