3-Phase Output Reactor Reduces Harmonics Protects Motor Windings Suitable for VFD Applications IP00 Protection Screw/Flat-type Connections UL/CSA Recognized

Product description

The Siemens 4EP3701-3US00 is a 3-phase output reactor designed to mitigate harmonics and protect motor windings from voltage spikes. It operates with a nominal voltage (Un) of 460V and has a maximum continuous current (Ithmax) of 6.1A at 120Hz. The reactor features a switching frequency (F cycle) of 3 kHz and a rated inductance (LN) of 3.47 mH.

Output reactors like the 4EP3701-3US00 are crucial components in variable frequency drive (VFD) systems and motor control applications. They help to reduce motor bearing currents, extend insulation life, and minimize electromagnetic interference (EMI) in industries such as manufacturing, HVAC, and material handling.

Stanlo Automation, a veteran-owned surplus parts distributor, provides the Siemens 4EP3701-3US00. Enhance your VFD system's performance and longevity by sourcing this essential component from us.
