Key specifications

• Amperage: 500A
• Poles: 3-Pole
• Voltage: 600V
• Part number: LM3500L

Why the LM3500L stands out for industrial applications

• Reliable three-phase protection: The 3-pole configuration ensures coordinated disconnection across all phases, reducing the risk of phase-to-phase faults.
• High-current capability: With a 500A rating, it’s suited for main distribution panels, motor control centers, and other heavy-load circuits where robust overcurrent protection matters.
• Versatile retrofit option: This unit is specifically referenced by part number LM3500L, making it a practical choice for replacements and updates in existing gear where matching specs is critical.
• Clear compatibility signal: The provided notes emphasize confirming fit and ratings before ordering, helping you avoid mismatches in critical systems.

Ideal use cases

• Maintenance or retrofits in older switchgear and distribution panels that require a 600V, 3-Pole breaker with a 500A capacity.
• Replacement for worn or decommissioned units in industrial facilities with three-phase power needs.
• Panel modernization projects where aligning with the LM3500L’s specifications ensures continuity and safety.

Compatibility and installation notes

Before ordering, verify that your system’s ratings align with LM3500L specifications. Use the part number as your primary reference for compatibility to minimize installation delays. Confirm, on-site, that the panel, bus connections, and mounting hardware can accommodate a 3-Pole, 600V device rated at 500A. If in doubt, consult your facility’s electrical documentation or a licensed professional to ensure proper fit and safe operation.

Practical tips for maximum reliability

• Match the LM3500L to your existing control scheme and wiring method to preserve protection coordination.
• During retrofits, inspect surrounding components for wear or compatibility issues that could affect breaker operation.
• Keep the replacement schedule aligned with your preventive maintenance plan to reduce unexpected downtime.
