Lenze 384067 EZN2-017A001 EZN Series 3-Phase Mains Choke

The Lenze 384067 EZN2-017A001 is a 3-phase AC mains choke line reactor from the Lenze EZN Series, engineered to enhance power quality and protect frequency inverters in automated industrial systems. Designed for supply networks operating between 400 V AC and 480 V AC, this power conditioning component handles a rated continuous current of 17 A and provides a nominal inductance of 0.9 mH per phase. Installed on the line input side of a variable frequency drive or servo control panel, it smooths input current waveforms, mitigates lower-order harmonics, and shields sensitive drive rectifiers against rapid current transients and mains voltage spikes.

As a fully passive inductive component, commissioning the EZN2-017A001 does not require software installation, firmware flashing, parameter configuration, or active cooling systems. Integration relies on straightforward power wiring placed directly between the utility network and the drive input terminals. When preparing a spare or replacing a damaged unit, service technicians simply need to confirm physical terminal connections and ensure phase wiring is secure. ABC Industrial Parts can assist maintenance teams with acquiring tested replacement units to restore machine operation efficiently.

Maintaining this choke involves routine physical checks of line connections, input supply voltage levels, and thermal conditions. Because the unit is a sealed passive inductive module without internal active electronics, physical breakdown or insulation failure cannot be repaired on-site. When internal winding faults or mechanical damage occur, substituting the module with a matching unit is the most direct path back to full production reliability.
