Westinghouse | PB31600T | Circuit Breaker | 1600A | 3-Pole | 600V

Meet the Westinghouse PB31600T circuit breaker — a robust, three-pole protection solution engineered for demanding industrial power systems. With a 1600A rating at 600V, this unit is built to safely interrupt high-current three-phase circuits, delivering reliable protection for critical equipment and workflows.

• Amperage: 1600A
• Poles: 3-Pole
• Voltage: 600V
• Part number: PB31600T
• Applications: maintenance, retrofit, and replacement where matching specs are required

The PB31600T stands out for environments that demand strong, dependable circuit protection in large, three-phase electrical distributions. It’s designed to slot into panels and systems that require a high-capacity breaker capable of handling substantial load demands while preserving safety and control across the distribution network.

Why this matters for your operation

• Supports high-demand facilities—industrial, manufacturing, and data-center-like environments where reliable 3-phase protection at 600V is essential.
• Three-pole configuration ensures synchronized interruption across all phases, minimizing arc faults and unbalanced loads during trips.
• High amperage capacity makes it suitable for main feeder protection or large branch circuits within compatible panels.

Compatibility and purchasing guidance

Notes: Confirm fit and ratings before ordering. The PB31600T part number is the best reference for compatibility, helping you align with the exact panel build, bus configuration, and trip characteristics required by your system.

Ideal use cases

• Replacing a failed or worn-out breaker in a large three-phase distribution panel
• Retrofit projects that upgrade panel capacity and reliability in industrial facilities
• Maintenance scenarios where matching the PB31600T’s specifications minimizes downtime and ensures continuity

Practical tips for deployment: keep system documentation handy to verify panel model and required trip ratings, and use the PB31600T as a direct, spec-midelity replacement where the 3-Pole, 600V, 1600A configuration matches your design. This approach helps maintain consistent electrical protection, reduces the risk of incompatibilities, and supports safer, more predictable maintenance windows.
