Siemens 5SL5263-7RC MCB 63A 2-Pole C Characteristic 10kA DC

The Siemens 5SL5263-7RC is a SENTRON 5SL5 miniature circuit breaker (MCB) specifically designed for DC circuit protection. This Siemens MCB features a 63 A rated current, 2-pole configuration, C tripping characteristic, 440 V DC maximum operating voltage and 10 kA short-circuit breaking capacity. Siemens product data confirms the device as a 2-pole DC MCB with C characteristic and a maximum DC operating voltage of 440 V.

The Siemens 5SL5263-7RC 63A 2-pole DC MCB is designed to protect suitable DC electrical circuits against overload and short-circuit conditions. Unlike a standard AC MCB, this product belongs to the Siemens 5SL5 DC range and is intended for applications where DC-specific circuit interruption is required.

With a 63 A rated current, the 5SL5263-7RC is suitable for higher-current DC circuits where the connected load, conductor capacity and system protection requirements match the device rating. Its C tripping characteristic provides a defined tripping response for suitable circuits with moderate starting or transient currents.

The 2-pole construction makes this MCB suitable for compatible DC systems requiring two-pole switching and protection. This configuration is useful for DC distribution panels, industrial control systems, battery-related applications, power electronics and other suitable DC installations.

The 10 kA breaking capacity provides the specified short-circuit interruption capability for applicable DC protection arrangements. In DC systems, correct circuit configuration and wiring are especially important because DC arcs behave differently from AC arcs. The manufacturer's specified application and connection arrangement should therefore always be followed.

The 440 V DC operating voltage makes the 5SL5263-7RC suitable for high-voltage DC applications within its specified rating. The exact voltage, polarity, pole connection and prospective short-circuit current should be verified before installation.

Benefits

The Siemens 5SL5263-7RC provides dependable circuit protection for applications requiring a 63 A, 2-pole DC MCB with C characteristic and 10 kA breaking capacity. Its dedicated DC design makes it suitable for applications where conventional AC miniature circuit breakers may not provide the required DC interruption performance.

The 63 A current rating allows the device to protect suitably designed higher-current DC circuits. Proper coordination with the connected load, cable capacity and upstream/downstream protection is essential to ensure that the MCB operates correctly under normal and fault conditions.

The C tripping characteristic provides a defined response for suitable DC circuits where moderate transient or starting currents may occur. This can make the MCB suitable for selected industrial equipment, DC control systems and other compatible loads.

The 2-pole configuration provides coordinated protection and switching for compatible DC circuits. This is useful where two poles require protection or switching within a DC distribution or control system.

The 10 kA short-circuit breaking capacity provides substantial fault-interruption capability for suitable installations. Because DC fault interruption depends strongly on voltage and circuit configuration, the actual installation should be checked against the Siemens-approved application conditions.

The 440 V DC maximum operating voltage makes the 5SL5263-7RC suitable for a range of higher-voltage DC applications. Siemens product data specifies DC operation, 440 V maximum operating voltage, IP20 protection with connected conductors, and compatibility with supplementary devices.

The product also features a halogen-free, sealable and silicon-free construction, according to the available product data, making it suitable for professional panel and equipment applications.
