Industrial LAB3350 350A 3-Pole 600 V Circuit Breaker

Engineered for rugged industrial power distribution, the LAB3350 is a 350 A, 3-pole, 600 V circuit breaker designed to protect and simplify your electrical infrastructure. Built for demanding environments, it provides reliable interruption of fault currents across a three-phase system, helping protect motors, drives, and critical loads from overloads and short circuits.

Why this matters — in a three-phase network, balanced protection across all phases reduces the risk of equipment damage and downtime. The LAB3350's three-pole configuration ensures all lines are managed together, delivering consistent protection for every phase.

Key features

• 350 A current rating handles high-load environments and motor starting surges without nuisance tripping.
• 3-pole design protects all three phases in 600 V systems for balanced stopping power.
• 600 V voltage rating suitable for typical industrial distribution networks.
• Part Number LAB3350 provides a precise, standardized replacement option for panel builders and maintenance teams.
• Rugged industrial construction built to withstand demanding factory floors, with secure mounting and reliable performance.
• Easy integration compatible with common 3P panels, switchgear, and MCCs, making retrofits and new installations straightforward.

Ideal for

• Main disconnects in 3-phase distribution panels for manufacturing lines and process equipment.
• Feeder protection for motors, conveyors, pumps, and presses in industrial facilities.
• Retrofit projects upgrading older circuits to a modern 350 A, 3-pole 600 V solution.

What sets LAB3350 apart

Compared to smaller or single-phase breakers, this 3-pole LAB3350 ensures simultaneous interruption of all live conductors, reducing the risk of phase imbalance and cascading faults. Its 350 A rating places it in the ideal range for mid-to-high-demand lines where a single device must cover multiple loads.

Tips for fast, reliable setup

• Verify compatibility with your panel's busbar configuration and stabs before replacement.
• Use the LAB3350 as the main protective device for multi-line feeders in 3-phase systems to centralize protection.
• Store spares in known-good condition and label circuits clearly for quick maintenance.
