Siemens 4EP3700-2US00 Choke Inductor For Industrial Equipment

Siemens 4EP3700-2US00 is a three-phase mains line reactor (choke) designed for frequency converters and industrial drives. Rated for 480 V three-phase input, it provides an inductance of 0.397 mH with about 2% impedance and a line-to-neutral current rating of 31.95 A; it uses screw-terminal connections and carries IP00 protection with insulation class B, reflecting a 40°C temperature rise rating. UL/CSA recognized and EN 61558-2-20 compliant, this Siemens line reactor is intended for motor drives and other three-phase power systems to condition the input and mitigate switching transient effects and harmonics.
