Square D | LE36500LI | Circuit Breaker | 3-Pole

Introducing the Square D LE36500LI 3-Pole Circuit Breaker—a robust solution designed for maintenance, retrofit, and replacement projects where exact specifications matter. This 3-Pole unit is built to safeguard three-phase electrical systems with reliable, consistent performance, making it a dependable choice for Commissioning and ongoing panel health.

Compatibility and fit

• Poles: 3-Pole — ideal for three-phase circuits that require coordinated interruption across all conductors.
• Part reference: LE36500LI — use this exact part number as the primary reference to confirm compatibility with your panel and circuitry.
• Important verification: Before ordering, verify your panel labeling and ratings to ensure this LE-series breaker is acceptable for the specific application.

Use cases

• Maintenance: replace aging or worn breakers to restore protection without redesigning the panel.
• Retrofit: upgrade legacy installations to current LE-series components that match existing three-phase layouts.
• Replacement: substitute a failed or obsolete 3-pole breaker to minimize downtime and keep the system operating safely.

What makes this LE36500LI different

• Exact part reference for fast, accurate ordering and reduced compatibility risk with Square D panels that accept LE-series breakers.
• Designed for three-phase protection, ensuring synchronized disconnection across all three lines to safeguard motors, compressors, and other three-phase equipment.
• Streamlined maintenance workflow: with a definitive part number, you can source, stock, and replace with confidence without guessing about fit.

Practical guidance for installation and selection

• Always power down the panel and verify de-energization before work; follow local electrical codes and safety practices.
• Confirm the panel’s compatibility with LE-series breakers and that the amperage and interrupting rating align with the circuit requirements.
• Choose this model when your system demands a three-pole, three-phase protection solution and the LE36500LI aligns with your panel’s labeling.
• If your project calls for a different pole count or a different LE-series variant, consider the corresponding LE-series models that match your panel’s specifications.

Ideal for

• Electrical contractors performing panel upgrades and replacements in commercial or light industrial facilities.
• Facility engineers maintaining reliability in three-phase distribution networks.
• Retrofit projects where matching the exact part number ensures seamless panel compatibility and minimized downtime.

Maintenance and longevity tips

• Store and handle in a clean, dry environment to preserve contact surfaces and internal mechanisms.
• Keep spare LE-series breakers with the same part number on hand to shorten service intervals during preventive maintenance.
• Document compatibility checks in your maintenance log—record the panel model, LE36500LI reference, and the verified ratings for future servicing.
