It reduces harmonic distortion and limits inrush current on the input side of the drive, protecting both the drive and upstream equipment. Rated for 400/480 V AC at 50/60 Hz, it carries a maximum continuous current of 18 A and a rated operational current of 16.2 A. The inductance is 1.6 mH, and the relative inductive voltage drop is 4% at rated conditions. The 4% voltage drop is typical for a line reactor intended to smooth the drive's rectifier stage without excessive voltage sag. The choke is IP00 rated — open frame, no enclosure. It mounts inside a panel or cabinet, not on a DIN rail. Dimensions are 0.178 m wide by 0.153 m tall by 0.105 m deep. Allow clearance around it for airflow; the combined copper and iron losses total 60.6 W at full load, which must be dissipated within the enclosure. Terminals are screw-type for the main circuit, accepting standard power wiring. Verify the terminal size against your cable gauge before panel layout. Thermal class B insulation per IEC 60085 means the winding temperature rise is limited to 80 K over a 40 °C ambient — adequate for most industrial panel environments. This part carries UL/CSA recognition per EN 61558-2-20, so it is accepted for panel builds shipped into North American markets without additional agency review.","metaTitle":"Siemens 4EP3700-7US00 Mains Choke, 3-Phase, 18A, 1.6 mH","metaDescription":"Siemens 4EP3700-7US00 mains choke for variable frequency drives. 3-phase, 480V AC, 18A max, 1.6 mH, 4% voltage drop.
