SCHNEIDER ELECTRIC VW3A4554

Schneider Electric VW3A4554 Altivar Line Choke Description The VW3A4554 is a high-performance three-phase line choke designed by Schneider Electric for its Altivar series of variable speed drives. This component is essential for improving power quality and protecting the drive from disturbances on the mains supply. It effectively reduces harmonic distortion (THDi), limits current peaks, and mitigates overvoltages, thereby extending the service life of the drive and connected motor. Specifications Manufacturer: Schneider Electric Part Number: VW3A4554 Product Type: Line Choke / AC Reactor Rated Current: 31 A Inductance: 1 mH Network Frequency: 50/60 Hz Phases: 3-phase Compatibility: Specifically for Altivar 61 and Altivar 71 series drives Thermal Losses: 100 W Weight: Approx. 8 kg Label Info Brand: Altivar / Telemecanique Model: VW3A4554 Specs: L(mH) 1, I(A) 31, F(Hz) 50/60 Insulation Class: CEI:60076-6-N.I:1.1kV Application This line choke is typically installed on the input side of a variable frequency drive (VFD) in industrial applications such as HVAC, pumping, and material handling to ensure compliance with power quality standards and to enhance system reliability. Country of Origin This product is made in the Czech Republic (CZ). CO2 Impact Choosing this reused line choke prevents the emission of approximately 320 kg of CO2, which is comparable to the carbon footprint of its new production. This is a sustainable choice for your operations. Availability This is an obsolete item, available as a refurbished spare part. Ideal for repairs and maintenance of existing installations.

Its main purpose is to reduce harmonic distortion caused by the variable speed drive on the mains power supply. It also helps protect the drive from voltage spikes and limits inrush current. Question? Is this choke compatible with modern Altivar Process drives like the ATV600 or ATV900 series?No, the VW3A4554 is specifically designed and rated for the older, now obsolete, Altivar 61 and Altivar 71 series drives. Using it with other drives is not recommended as the performance and protection characteristics may not match. Question? What are the signs that a line choke needs replacement?Signs of failure can include overheating (discoloration or melting of the varnish), audible buzzing or humming that is significantly louder than normal, or physical damage to the windings or core. A faulty choke can lead to increased harmonics and potential damage to the drive. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
