3-Phase Line Reactor Protects Frequency Converters Reduces Harmonics UL/CSA Recognized 480V AC Rated Screw Terminals IP00 Enclosure

Product description

The Siemens 4EP3700-2US00 is a 3-phase line reactor designed to protect frequency converters (FU) from voltage spikes and harmonic distortion. It operates with an input voltage of up to 480V AC and has an operating current of 31.95A, with a maximum current of 35.5A. The reactor features a low impedance of 2% (UK) and an inductance (LN) of 0.397 mH, contributing to smoother current flow and reduced electromagnetic interference.

Constructed with screw-type terminals for main current circuit connection, this reactor is rated for IP00 protection, meaning it requires enclosure. It has a thermal class of 40°C / B and is UL/CSA recognized. The dimensions are approximately 0.178m width, 0.153m height, and 0.105m depth. This reactor is essential for improving the reliability and lifespan of variable frequency drives.
