Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 359485 (ELN1-0900H005) is a 3-phase mains line choke designed within the Lenze Drive Accessories family for installation in AC variable frequency drive systems. Operating on 3-phase electrical networks up to 480 V AC nominal, this heavy-duty passive line reactor provides a inductance rating of 9.0 mH and supports a rated current capacity of 5 A. Commonly deployed across automotive manufacturing, packaging machinery, material handling systems, and textile production lines, the choke acts as a protective power quality buffer between the distribution grid and connected frequency inverters. Its primary function is to suppress mains current harmonics, smooth input waveforms, and shield sensitive drive electronics from voltage transients and line surges.
Integrating a replacement Lenze 359485 line choke into an existing drive panel is a simple hardware task due to its passive design. Because the component contains no active digital control circuitry, commissioning a spare unit requires zero engineering software, parameter transfers, or firmware alignment. Maintenance personnel must verify that the 3-phase supply does not exceed the maximum 480 V AC rating and ensure that the connected drive is rated up to 5 A current. ABC Industrial Parts supplies direct replacement line reactors to assist facilities in quickly restoring operational readiness without complex setup routines.
As a passive inductive component, the ELN1-0900H005 does not feature LED indicators, diagnostic registers, or communication ports. Maintenance routines rely on initial physical and electrical verification, including checking line connections for secure seating, measuring phase balance across the 3-phase supply, and inspecting choke windings for signs of thermal stress. Internal electrical shorting or winding insulation degradation cannot be repaired in the field; replacing a degraded unit with a tested spare from ABC Industrial Parts offers the most reliable path back to full machine operation.

Replacement and Spare Part Considerations
When replacing a Lenze 359485 (ELN1-0900H005) mains line choke, verify that the application electrical parameters match the unit's key ratings: 3-phase power distribution up to 480 V AC, 5 A nominal current capacity, and 9.0 mH inductance per phase. Matching these core specifications protects downstream drive capacitor banks and ensures effective harmonic dampening.
As a component of the legacy ELN1 series, the 359485 serves as a direct drop-in replacement for existing drive panel setups. For long-term facility planning or system modernizations, the ELN3 series is available as a successor family, provided that equivalent current and inductance ratings are selected for the connected frequency inverter.
Because line reactors are entirely passive physical hardware, swapping out a faulty unit requires only physical mounting and terminal re-wiring. No backup files, programming cables, memory cards, or commissioning software parameters need to be saved or transferred.
Frequently Asked Questions
Does the Lenze 359485 ELN1-0900H005 line choke require software configuration?
No. The Lenze 359485 is a passive hardware line reactor that requires no programming software, parameter transfers, or digital commissioning.
What are the primary electrical specifications for the 359485 choke?
The choke provides an inductance rating of 9.0 mH and a nominal current rating of 5 A across 3-phase supply systems up to 480 V AC maximum.
What function does the ELN1-0900H005 perform in a drive installation?
It dampens peak switching currents, suppresses mains voltage transients, and reduces harmonic distortion on input power lines leading to AC frequency inverters.
Which series serves as a recommended successor for the ELN1 line choke?
The Lenze ELN3 series serves as the recommended successor series for future upgrades or panel modernizations requiring similar current and inductance profiles.
How do you troubleshoot a suspect mains line choke?
Troubleshooting involves physical inspection for thermal damage or winding discoloration, confirming proper terminal torque, and verifying voltage balance across all three phases.
