Schneider VW3A4553 Line/Motor Choke for Altivar Variable Speed Drives

Where It Excels in Industrial Use

• Input Line Protection
The Schneider VW3A4553 is a three-phase line/motor choke designed for Altivar variable speed drives. Installed on the input side of the drive, it helps protect against mains overvoltage, voltage transients, and power quality disturbances while reducing harmonic current distortion.

• Motor Output Protection
When installed between the drive and the motor, the choke reduces motor insulation stress, limits output current peaks, and helps protect motors connected with long cable runs.

• Industrial Automation Systems
Suitable for conveyors, packaging machinery, HVAC equipment, pumping systems, compressors, material handling equipment, and general industrial automation using Schneider Altivar drives.

• Improved Power Quality
The choke minimizes harmonics, reduces electromagnetic disturbances, and enhances overall system reliability, particularly where multiple drives share the same power supply. 

Key Strengths at a Glance

• Dual Application
Can be used as either a line choke or a motor choke, providing installation flexibility for drive systems.

• 17 A Rated Current
Designed for three-phase applications with a continuous rated current of 17 A.

• 2 mH Inductance
Features 2 mH inductance, providing effective harmonic reduction and improved protection against electrical disturbances.

• Industrial Construction
Built for industrial environments with a robust open-frame design suitable for installation inside electrical control cabinets.
