ABB OTDC400USV12 - 400A, 3-Pole, Disconnect Switch

ABB OTDC400USV12 is a robust 400 A, 3-Pole Disconnect Switch engineered for demanding industrial and commercial installations. Designed to support proper lockout/tagout procedures, it delivers dependable electrical isolation and reliable disconnection under load, making maintenance and service safer and more predictable in harsh environments.

Key Benefits

• 400 A, 3-Pole design provides complete isolation for three-phase systems, ensuring all live conductors can be safely separated when needed.
• Lockout/Tagout readiness supports standard safety protocols, helping teams prevent accidental energization during maintenance.
• Reliable disconnection under load delivers a clear, intentional break in the circuit, reducing downtime and enhancing operator safety.
• Durable industrial construction built to withstand the rigors of everyday use in busy facilities, delivering long-term service life.
• ABB engineering reliability backed by the brand’s reputation for robust power control components and dependable performance in critical applications.

Ideal Applications

• Main isolation for three-phase motors, feeders, and process equipment in manufacturing plants.
• Electrical isolation points within power distribution panels, switchgear, and control centers.
• Emergency shutdown and routine maintenance scenarios where safe de-energization is essential.
• Industrial and commercial environments where strict lockout/tagout procedures are part of daily safety protocols.

Safe Operation and Practical Considerations

To maximize safety, pair the OTDC400USV12 with established lockout/tagout devices and comply with applicable electrical codes and safety standards. Use the switch as the primary isolation point in the circuit path, verify complete de-energization before servicing, and ensure all tags and seals remain in place during maintenance. After work is complete, remove lockout devices only after confirming that the circuit is ready to be re-energized.
