ABB OTDC400US22 - 400A, 1000V, 4-Pole, Disconnect Switch

Meet the ABB OTDC400US22 — a purpose-built disconnect switch designed for safe, reliable electrical isolation in demanding industrial and commercial environments. With a robust 400A current rating and a 1000V voltage rating, this 4‑pole device delivers true isolation across all lines, supporting lockout/tagout procedures and secure maintenance work without compromise.

Why the OTDC400US22 stands out

In power systems where safety and uptime matter, this disconnect switch provides dependable performance under load. The 4‑pole configuration ensures complete de-energization of all conductors in typical 3‑phase plus neutral setups, reducing the risk of residual current during service. Built for long-term durability, it’s engineered to stand up to frequent operation in demanding environments.

Key advantages

• Complete line isolation with a 4‑pole design that protects all conductors in multi‑voltage systems
• High-load capability rated for 400A, making it suitable for motors, feeders, and switchgear banks
• Voltage resilience rated up to 1000V to accommodate a range of industrial power supplies
• Lockout/tagout compatible to support safe maintenance and compliance with safety protocols
• Disconnection under load capability for reliable operation during system transitions or testing
• Durable, purpose-built design for long service life in harsh industrial environments

Ideal applications

Use the OTDC400US22 to isolate critical power sources in motor control centers, manufacturing lines, large HVAC and processing equipment, transformer banks, data center auxiliary power feeds, and other facilities where safe, reliable isolation is essential for maintenance and shutdown procedures.

Practical considerations and setup tips

• Plan installations around complete line isolation to support effective lockout/tagout workflows
• Ensure the switch is integrated with compatible switchgear and enclosures designed for high-current, high-voltage applications
• Coordinate with safety programs to align with routine maintenance and testing schedules
• Keep a clear operating procedure nearby to guide technicians through safe disconnection and re-energization steps
