The Square D MGL36350 350A 3P 600V Circuit Breaker is a rugged protection device designed for panelboards, load centers, and distributed electrical systems. Built to support demanding 3‑phase environments, this breaker helps you maintain safe, reliable power delivery while preserving your existing installation by using the exact part number required for retrofit and maintenance planning.

  • Three-pole protection for 3‑phase systems: Provides protection across all three conductors, aligning with standard industrial distribution architectures.
  • 350 A continuous rating: Capable of safeguarding substantial feeder loads while delivering reliable short‑circuit protection.
  • 600 V maximum system voltage: Suitable for higher voltage applications typical in commercial and industrial layouts.
  • OEM-grade reliability from Square D: Designed to integrate smoothly with panelboards and load centers within the Square D MGL family, ensuring consistent protection profiles.
  • AmpState support: Available for order with assistance to verify fit and compatibility, helping you streamline procurement and avoid surprises on site.

Who benefits most from the MGL36350? electrical contractors, facilities managers, and panel builders who need a dependable, compatible 350 A, 3‑pole, 600 V circuit breaker that fits existing infrastructure without requiring redesigns. It’s especially valuable in retrofit projects where maintaining the same part number minimizes configuration changes, and in maintenance planning where stocking the exact model reduces downtime during replacements.

Use cases include upgrading distribution feeders in existing panelboards, replacing aging protection devices in load centers, and ensuring consistent protection profiles across multi‑section electrical systems. If you’re verifying compatibility for a retrofit or replacement project, AmpState offers guidance to confirm fit and ensure a seamless swap, so your installation stays on schedule without guesswork.
