5SV3344-4KK14 SIEMENS

The 5SV3344-4KK14 is a four-pole residual current operated circuit breaker (RCCB) meticulously engineered by Siemens to provide advanced protection against electrical hazards. This RCCB is specifically designed to detect residual currents, which indicate potential insulation faults or leakage currents, thereby preventing electrical shocks and fire hazards. Featuring a Type B+ tripping characteristic, it is particularly sensitive to both AC and pulsating DC residual currents, ensuring comprehensive protection in diverse applications. The short-time delayed tripping mechanism enhances selectivity in electrical systems, preventing nuisance tripping due to transient faults. With a rated current (In) of 40 A and a residual current sensitivity (IΔn) of 30 mA, this RCCB is suitable for a wide range of residential, commercial, and industrial applications. It operates at a rated voltage (Un AC) of 400 V, seamlessly integrating into standard three-phase electrical systems. The 5SV3344-4KK14 RCCB offers reliable and precise protection, enhancing the safety and reliability of electrical installations. Its robust design and adherence to stringent quality standards ensure long-term performance and peace of mind. This device is an essential component for modern electrical safety systems.
