Eaton | LM3450 | Circuit Breaker | 450A | 3-Pole | 600V

Engineered by Eaton, the LM3450 circuit breaker delivers reliable protection for three‑phase electrical systems. With a 450A rating, a 3‑pole configuration, and a 600V maximum, this unit is designed for durability in maintenance, retrofit, and replacement projects where exact specifications matter.

• Amperage: 450A
• Poles: 3‑Pole
• Voltage: 600V
• Part Number: LM3450
• Ideal for: Maintenance, Retrofit, Replacement

Notes to ensure a perfect fit: confirm the panel’s compatibility by matching the exact part number to your equipment before ordering. The LM3450 part number is the best reference for compatibility with Eaton panels and bus configurations.

Why this matters: a precisely matched breaker minimizes downtime and maintains reliable overcurrent protection for three‑phase systems. The LM3450’s 3‑pole design supports balanced protection across all phases, helping prevent faults from propagating and protecting downstream equipment.

• Upgrading or restoring service in industrial panels that require 450A, 3‑pole, 600V protection; replacing a failed unit with a direct LM3450 compatibility match; retrofitting systems to preserve original protection characteristics.
• maintenance teams, panel assemblers, electrical engineers, and facilities managers overseeing 3‑phase distributions up to 600V.

Practical tips for ensuring a smooth installation: have the panel’s data plate and wiring diagram handy, and verify that the current rating, voltage rating, and pole configuration align with the LM3450’s specifications. Rely on the LM3450 part number as your primary reference to avoid mismatches and ensure seamless replacement in your Eaton‑designed ecosystem.
