Westinghouse DS464R - 200A, 3-Pole, Fused Disconnect Switch

The Westinghouse DS464R is a robust 200A, 3-pole fused disconnect switch built for demanding industrial and commercial environments where safe electrical isolation is non-negotiable. This unit is purpose-built to support lockout/tagout procedures and provides dependable disconnection under load, helping maintenance teams work safely without sacrificing uptime or reliability.

Key benefits that matter in the field

• High-current capability — designed for up to 200A circuits, making it suitable for feeders, motor circuits, and essential plant equipment.
• Three-pole design — a complete, phase-balanced disconnect that isolates all conducting paths, reducing the risk of partial energization during servicing.
• Integrated protection — the fused configuration provides overload protection within the disconnect path, enhancing overall system safety and component longevity.
• Safe isolation with LO/TO readiness — built to align with standard lockout/tagout practices, enabling clear, verifiable de-energization before maintenance begins.
• Durability in tough environments — engineered to endure the rigors of continuous operation in industrial or commercial facilities, delivering reliable performance over time.

Ideal applications

• Manufacturing floors and assembly lines requiring dependable circuit isolation for maintenance and upgrades.
• Industrial automation and equipment rooms where motors, drives, and feeders need quick, safe disconnection under load.
• Commercial facilities with critical power distribution that must isolate sections without interrupting surrounding systems.

Practical considerations for deployment

• Plan for safe, verifiable de-energization by pairing the DS464R with proper lockout/tagout procedures and tamper-evident devices.
• Ensure routing of conductors supports full isolation of all three poles during service, reducing the chance of residual energization.
• Coordinate fuse selection and replacement with system load profiles to maintain optimal protection without unnecessary downtime.
• Integrate the DS464R into panels and enclosures that accept standard industrial disconnects to streamline installation and future maintenance.
