4EU3951-5UB00-0A SIEMENS

The 4EU3951-5UB00-0A is a three-phase mains choke designed for FU applications, ensuring optimal power quality and harmonic mitigation. It is engineered to operate at a rated voltage (UN1) of 500V and a frequency (F1) of 50Hz. The choke boasts a maximum thermal current (ITHMAX 1) of 1120A and a rated current (I LN) of 1008A, providing robust performance under demanding conditions. With a voltage drop (UK) of 2% and an inductance (LN) of 0.0164 mH, it effectively smooths out current waveforms and reduces harmonic distortion. The choke is designed for a maximum ambient temperature (TA) of 40°C and adheres to insulation class H, ensuring reliable operation in elevated temperature environments. It features an IP00 protection rating, indicating that it is not protected against water or dust ingress and is equipped with flat-type terminals for secure and convenient connections. Compliant with EN 61558-2-20 standards and UL/CSA recognized, this choke guarantees safety and performance in various industrial applications. This choke is a crucial component for minimizing line disturbances and enhancing the efficiency of electrical systems.
