Square D | MXF36350G | Circuit Breaker | 350A | 3-Pole | 600V

Meet the Square D MXF36350G circuit breaker — a robust, high-capacity protection device designed for demanding 3‑phase power systems. With a 350A rating and a 3‑pole configuration, this unit is built to safeguard large feeders and critical loads in industrial and commercial environments operating up to 600V.

Designed for real-world maintenance, retrofit, and replacement scenarios, the MXF36350G delivers the exact specifications you need to keep your power distribution running smoothly. This isn’t a generic drop-in part — the part number MXF36350G is the most reliable reference for compatibility with compatible Square D panels and accessories.

Key benefits you’ll notice

• High-current protection: 350A capacity to reliably protect heavy-load circuits without frequent tripping.
• Three-pole, three-phase protection: Ensures balanced interruption across all phases, improving system safety and fault isolation.
• 600V maximum rating: Suitable for standard industrial distribution and commercial power networks that demand higher voltage handling.
• Precise compatibility: The MXF36350G is your best reference for matching panel compatibility and intended electrical architecture.
• Efficient maintenance and retrofits: Ideal for upgrading aging breakers or replacing failed units with minimal downtime.

Ideal use cases

• Retrofit projects where a 350A, 3-pole breaker is required to fit existing panel spaces without reconfiguring wiring.
• Replacement of a failed 3-pole breaker in 600V distribution systems that feed large motors, processing equipment, or HVAC infrastructure.
• New or updated distribution setups in light industrial or commercial facilities needing reliable, scalable protection for high-load feeders.

How to ensure you’re ordering the right part: always verify the fit and ratings against your panel’s documentation. The MXF36350G part number serves as the definitive reference for compatibility, so cross-check it with your equipment’s required specifications before purchasing.

Installation and safety note: handle and install this breaker in accordance with applicable electrical codes and standards. Use qualified personnel, de-energize circuits prior to service, and follow proper lockout/tagout procedures to protect personnel and equipment.
