Siemens 4EM4911-7CB00 Line Commutating Reactor
Siemens 4EM4911-7CB00 1-Phase Line Commutating Reactor.
The Siemens 4EM4911-7CB00 is a line commutating reactor designed for rectifier applications. It is a single-phase reactor with a rated voltage of 400V (Un1). Key specifications include a maximum thermal current (Ithmax) of 10A at 50Hz (F1), a line-to-neutral inductance (LN) of 4.84 mH, and a line-to-line impedance (UK) of 4%.
This reactor is crucial for smoothing current and reducing harmonics in power electronic systems, particularly in rectifier circuits. It finds applications in industrial power supplies, motor drives, and other systems where clean DC power is required from AC sources. Its IP00 protection rating indicates it's intended for installation within an enclosure.
