Allen-Bradley 1321-3RA100-B Line Reactor Transformer

Allen-Bradley 1321-3RA100-B is a 100 A, three-phase line reactor in a NEMA 1 enclosed housing designed for use with 200–690 V AC power networks, providing inrush limitation and current smoothing for motor drives and other inductive loads. This RA-series enclosure delivers roughly 0.3 mH of inductance and an impedance of 3–5%, enabling targeted reactance to match drive specifications while maintaining a compact form factor for panel installations in industrial environments. As part of the 1321 Power Component family, it is intended for line-side installation on three-phase drives to help manage power quality in AC drive systems by shaping current draw and reducing voltage transients. The unit carries IP11 protection, suitable for indoor use in standard electrical rooms, with a rugged NEMA 1 enclosure that supports reliable operation in typical manufacturing settings.
