5SV3644-6KK01 SIEMENS

The 5SV3644-6KK01 is a four-pole residual current circuit breaker (RCCB) meticulously engineered by Siemens to deliver advanced protection against electrical faults. This RCCB is specifically designed as a Type A device, rendering it sensitive to both alternating current (AC) and pulsating direct current (DC) residual currents, thereby enhancing its ability to detect a broader spectrum of fault conditions. Featuring a short-time delayed tripping characteristic, the 5SV3644-6KK01 is adept at preventing nuisance tripping caused by transient or surge currents, ensuring operational continuity in sensitive applications. With a rated current (In) of 40A, this RCCB is suitable for circuits with moderate to high current demands, providing reliable protection without compromising performance. The device is configured to trip at a residual current (IΔn) of 300mA, offering a balance between sensitivity and immunity to unwanted tripping, making it ideal for applications where a higher level of earth fault protection is required. It is designed for a rated voltage (Un) of 400V AC, aligning with standard industrial and commercial power systems. The 5SV3644-6KK01 is commonly employed in distribution boards and electrical panels to safeguard against earth leakage currents, preventing electrical shocks and minimizing the risk of fire hazards. Its robust construction and adherence to stringent quality standards ensure long-term reliability and consistent performance in diverse environmental conditions. This Siemens RCCB provides a critical safety component for electrical installations, enhancing overall system safety and protecting both equipment and personnel.
