Siemens 1-Phase Line Commutating Reactor 4EM4700-8CB00
Siemens 1-Phase Line Commutating Reactor for Rectifier Applications.
The Siemens 4EM4700-8CB00 is a single-phase line commutating reactor designed for use in rectifier circuits. It has a rated input voltage (Un1) of 230V, a maximum short-time current (Ithmax) of 20A at 50Hz, and a rated inductance (LN) of 0.637mH. The reactor has a nominal line current (I LN) of 18A and a short-circuit voltage (UK) of 2%. It features a temperature rise of 40K and an insulation class of B, with an IP00 protection rating.
This reactor is typically used to smooth out current ripples and limit inrush currents in rectifier applications, ensuring stable DC output and protecting downstream equipment. It finds applications in power supplies, battery charging systems, and industrial DC power units within sectors such as manufacturing, automation, and energy systems.
