Allen‑Bradley 3LR6A is a three‑phase line reactor with Sine‑Guard technology from Trans‑Coil (TCI), designed to condition and protect power feeds to drives and rectifiers. It is rated for up to 600 V maximum and 6 A maximum current, making it suitable for safeguarding six‑pulse rectifiers and variable‑frequency drives in industrial automation. Typical installations place the reactor on the input side of the drive, and units are commonly offered with a NEMA 3 enclosure for indoor/outdoor use. By smoothing the input current and limiting dv/dt, the 3LR6A helps improve power quality and extend drive life in demanding manufacturing environments.
