Allen-Bradley 1494V-DS400 Disconnect Switch Assembly

Allen‑Bradley 1494V-DS400 Disconnect Switch Assembly is a 400 A, right‑hand, variable‑depth disconnect designed to isolate power in industrial control systems. As part of the 1494V family, the DS400 model supports electrical ratings up to 600 VAC and 250 VDC, making it suitable for high‑current AC and DC circuits in motor control centers, switchgear, and power‑distribution panels. The assembly features a flange‑operated design with a right‑hand operating mechanism and is intended for installation at variable depths to fit different enclosure configurations. Typical applications include isolating large motors, feeders, and control circuits within industrial facilities, where reliable de‑energization is required for maintenance and safety. The DS400 designation identifies the 400 A class of disconnect switches within the Series D/1494V lineup, and its documented electrical and installation data are available in Rockwell Automation’s technical literature for the 1494V-DS400/DSX400 family.
