Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 00325294, designated by model code ELN3-0160H012, is a 3-phase line reactor within the ELN family designed for supply-side power conditioning on variable frequency drives. Engineered to process 3-phase AC power up to 480 V AC with an operational threshold of 500 V AC, this passive mains choke delivers a continuous rated current of 16 A and a nominal inductance of 1.2 mH. By introducing precise inductive impedance between the grid and the inverter AC input, the device dampens power line voltage spikes, attenuates line current harmonics, and limits peak inrush currents during drive start-up and heavy acceleration cycles. This power conditioning action shields sensitive input rectifier diodes and DC link bus capacitors from electrical stress.
Integrating the ELN3-0160H012 into a power distribution system involves standard 3-phase AC input and output terminal connections wired between the incoming grid feed and the drive input terminals. The unit is optimized for compatibility with Lenze 8200 and Lenze 9300 series frequency inverters. As a fully passive inductive component, swapping out an existing unit does not require any software installation, firmware alignment, DIP switch configuration, or parameter configuration transfer. Maintenance teams can complete a replacement through straightforward physical mounting and proper high-current terminal wiring. ABC Industrial Parts can supply tested replacement hardware to minimize plant downtime during maintenance interventions.
Because the ELN3-0160H012 is a passive component without electronic control boards or status display LEDs, troubleshooting relies on standard electrical and thermal checks. System diagnostics involve verifying secure terminal connections, inspecting coil windings for signs of thermal discoloration, and performing phase-to-phase resistance and inductance measurements using standard test equipment. Unbalanced resistance across phases or internal short circuits signal severe coil degradation, which cannot be serviced in the field. When a hardware fault is identified, procuring a replacement reactor from ABC Industrial Parts offers a direct solution to restore system reliability.

Replacement and Spare Part Considerations
When selecting a replacement for the Lenze 00325294 ELN3-0160H012, ensure that both the continuous current rating of 16 A and inductance rating of 1.2 mH match the electrical requirements of the connected Lenze 8200 or 9300 drive. Using a choke with mismatched specifications can alter the total input impedance, potentially reducing harmonic suppression performance or causing thermal overload under continuous drive operation.
Since the ELN3-0160H012 contains no electronic circuitry, control software, or parameter memory, commissioning a spare requires no backup restore procedures or field tuning. Installation consists of mounting the unit securely inside the enclosure, maintaining proper ventilation clearances around the open windings, and ensuring line terminals are torqued according to power wiring standards.
