Square D | PXF36800LSIZ | Circuit Breaker | 800A | 3-Pole | 600V

The Square D PXF36800LSIZ circuit breaker is engineered for demanding industrial and commercial electrical systems, delivering dependable protection for 3-phase, 600V networks at up to 800A. This 3-pole device is designed for maintenance, retrofit, and replacement projects where exact specifications matter.

• Amperage: 800A
• Poles: 3-Pole
• Voltage: 600V

Built to align with Square D panels that require the PXF36800LSIZ reference, this breaker helps maintain coordination across protective devices and reduces the risk of mismatch that can compromise safety or performance.

• Exact part reference: The PXF36800LSIZ designation is your best reference for compatibility with compatible Square D panels.
• Ideal for maintenance and retrofit: Replace aging or failed breakers in existing 3-phase, 600V systems without needing panel changes.
• High-current reliability: Designed to handle 800A in a 3-pole configuration, protecting essential equipment and minimizing unplanned downtime.
• Versatile for commercial/industrial environments: Suitable for data centers, manufacturing floors, and large electrical distributions that use 600V three-phase power.

Use cases and scenarios:

• Replacing a failed 3-pole breaker in an existing 600V distribution panel that requires 800A rating.
• Retrofit projects where a direct part-for-part replacement is needed to maintain panel ratings and trip characteristics.
• Maintenance cycles in facilities with heavy machinery and multiple motors that rely on reliable three-phase protection.

How to verify compatibility and order confidently:

• Check that your panel requires a 3-pole, 600V, 800A device and that the part number matches PXF36800LSIZ.
• When in doubt, consult the panel label and wiring diagram, and reference the manufacturer's compatibility notes for Square D breakers.

Important ordering note: Confirm fit and ratings before ordering. The part number PXF36800LSIZ is the best reference for compatibility.
