Product description
Shipping
Westinghouse LA3400N is a robust circuit breaker designed for demanding electrical systems. Rated at 400A with a 3‑pole (three‑phase) configuration and a 600V maximum, this bolt‑on unit is built for maintenance, retrofit, and replacement projects where precise protection is essential. When downtime isn’t an option, the LA3400N provides reliable, straightforward panel integration that keeps critical circuits safeguarded.
Key capabilities
- Ampere rating: 400A
- Poles: 3‑Pole (three‑phase)
- System voltage: 600V
- Mounting: Bolt‑On for quick, secure panel installation
- Compatibility reference: Part number LA3400N (best reference for fit)
Why this breaker matters
In commercial and light industrial environments, protecting feeders and distribution paths from overloads and short circuits is critical. The LA3400N delivers dependable overcurrent protection for 400A, three‑phase circuits, while its bolt‑on design enables faster replacements and maintenance—reducing downtime and getting systems back to full operation sooner.
Ideal use cases
- Replacing a failed 400A, 3‑pole breaker in existing panels that require a 600V bolt‑on solution.
- Retrofits to modernize aging electrical systems without reconfiguring major panel components.
- New installations with heavy three‑phase loads where reliable, easy‑to‑install protection is needed.
Installation and compatibility tips
Always confirm fit and ratings before ordering. Rely on the part number LA3400N as the primary compatibility reference to ensure seamless replacement or retrofit. For safety and compliance, have a licensed electrician perform installation following local codes and manufacturer guidelines.
Care and ongoing protection
- Regularly inspect for signs of wear, overheating, or insulation damage and replace if needed.
- Keep the breaker and surrounding panel area clean and dry to maintain reliable operation.
- Follow official mounting torque recommendations and ensure a secure, defect‑free connection within the panel.
