Allen-Bradley 1321-DC32-2 DC Link Choke

The Allen-Bradley 1321-DC32-2 (1321-DC32-2) is a DC link choke designed for power conditioning and drive protection in industrial variable frequency drive systems. Operating within the direct current bus circuit, this component attenuates harmonic distortion, reduces alternating current ripple, and protects sensitive power electronics from line disturbances and excessive current surges. By smoothing bus voltage and limiting peak inrush currents, the choke promotes electrical stability and extends the operating lifespan of connected drives, power semiconductors, and downstream automation equipment. Built with a net weight of 10 kg, the unit provides robust construction suitable for demanding control cabinet integration, routine maintenance, system upgrades, and direct replacement in industrial environments. Proper installation in matching drive lineups ensures reliable circuit filtering and consistent operation across diverse manufacturing and process automation applications.
