Industrial 2TA400K 400A 2-Pole Circuit Breaker

Meet the Industrial 2TA400K 400A 2-Pole Circuit Breaker — a purpose-built protection device engineered for demanding electrical systems. With Part Number 2TA400K, this high-current breaker delivers reliable safety for industrial feeders and motor circuits, keeping downtime to a minimum and operations flowing smoothly.

Key advantages that elevate this breaker

• High-current protection: 400 A rating provides robust protection for heavy-load feeders, large motors, and mission-critical equipment.
• Two-pole design for safer disconnection: Simultaneously disconnects both conductors, reducing arc exposure and enhancing on-site safety during maintenance or fault events.
• Industrial-grade durability: Built to withstand the rigors of busy environments, frequent switching, and periodic maintenance in manufacturing, plants, and distribution centers.
• Clear part identification: Part Number 2TA400K ensures straightforward ordering, reordering, and cross-reference in inventory systems.
• Compatible with standard industrial panels: Designed to integrate with common panelboards and distribution configurations found in heavy-duty electrical installations.

Ideal use cases

• Main feeders in manufacturing lines that demand consistent, high-current protection

• Motor control centers and large equipment circuits where rapid, reliable interruption is essential

• Industrial distribution panels that require dual-pole isolation for safety and compliance

Why choose this over lighter-duty alternatives

• Unlike smaller or single-pole breakers, the 2-pole design provides synchronized disconnection of both conductors, reducing the risk of dangerous backfeeds and improving maintenance safety.
• The 400 A capacity is purpose-built for high-demand installations, offering greater protection and operational reliability than lower-rated devices in the same environments.
• Its industrial-grade construction is tailored for tougher conditions, helping minimize nuisance trips and extend service life in busy facilities.

Practical insights for procurement and installation

When stocking for maintenance or new builds, pair the 2TA400K with compatible high-current panelboards and service feeders to ensure seamless replacement or upgrade paths. For best results, verify panel compatibility and follow applicable electrical standards and local codes during installation. This part-numbered solution is designed to provide dependable, two-conductor protection that keeps critical systems online and safe.
