The Square D LAL36300MB 300A 3-Pole circuit breaker is your trusted solution for demanding electrical protection in commercial and industrial settings. Designed for maintenance, retrofit, and replacement projects, this authentic Square D component ensures you’re working with the exact spec required for safe, reliable operation.

  • Amperage: 300A
  • Poles: 3-Pole
  • Part number: LAL36300MB
  • Brand: Square D
  • Recommended use: Maintenance, retrofit, and replacement where matching specs are required
  • Important compatibility note: Confirm fit and ratings before ordering. The part number is the best reference for compatibility.

Why choose the LAL36300MB for your panel:

  • Exact-match reliability: As a genuine Square D component, it’s purpose-built to align with panels and configurations that call for the LAL36300MB, reducing guesswork during replacement.
  • High-capacity protection: A 300-amp, three-pole design supports substantial load centers, making it suitable for demanding commercial and light-industrial circuits.
  • Operational clarity: Clear part identification (LAL36300MB) helps you verify compatibility at a glance, speeding up maintenance cycles and audits.

Practical use cases and considerations:

  • Ideal for scheduled maintenance where existing hardware uses the LAL36300MB or requires an exact spec match.
  • Suitable for retrofit projects that upgrade or replace older breakers where a 300A, 3-pole configuration is appropriate.
  • Before purchasing, verify that your panel’s rating and bus configuration align with this exact part number to ensure a correct, safe installation.

Pro tips for a smooth replacement:

  • Keep the panel model and existing breaker information on hand to cross-check against LAL36300MB. The part number is your most reliable compatibility reference.
  • Power down the system and lockout/tagout the relevant circuit before replacement, and use proper PPE.
  • Consult a licensed electrician if you’re unsure about panel compatibility or installation procedures.
