It's built to EN 61558-2-20, the standard for chokes and reactors. Terminals are free conductor ends, so you'll land your own lugs or ferrules. This reactor sits between the supply and a VFD or between the drive and the motor. The 7% p impedance limits harmonic distortion and reduces peak currents on the DC bus. The 5 kVAR rating is the reactive power at rated voltage and frequency — that's the core sizing parameter. The 7% p impedance determines the voltage drop across the reactor at full load; 7% is a typical value for line reactors in industrial drives, providing a good balance between harmonic attenuation and voltage drop. The resonant frequency is 189 Hz, which is well above the 50 Hz fundamental and below typical switching frequencies, so it won't create a parallel resonance with the drive's DC bus capacitors. The 40 °C ambient rating (TA/ISOKL:40 /B) means it's rated for continuous duty at 40 °C ambient with Class B insulation (130 °C rise).","metaTitle":"Siemens 4EP3700-1BP00 Filter Reactor, 5 kVAR, 400 V, 50 Hz","metaDescription":"Siemens 4EP3700-1BP00 filter reactor, 3-phase, 5 kVAR, 400 V, 50 Hz, 7% p, IP00, free conductor ends.
