LM3800L | Circuit Breaker | 800A | 3-Pole | 600V

Meet the LM3800L industrial circuit breaker — a rugged 800A, 3-pole protection device designed for demanding electrical environments. Engineered for maintenance, retrofit, and replacement needs, it delivers reliable, coordinated safety across all three phases in 600V systems.

Key specifications at a glance

• Amperage: 800A
• Poles: 3-Pole
• Voltage: 600V
• Reference: Part number LM3800L is the best compatibility reference

Why this breaker stands out

The LM3800L is built for industrial duty, delivering synchronized interruption across all three phases to protect motors, drives, and power distribution panels from overloads and faults. Its 800A rating supports heavy-load applications typical in manufacturing, processing plants, and large facilities, while the 3-pole configuration ensures predictable, safe shutdowns—minimizing downtime and equipment risk during maintenance or fault events.

Ideal use cases

• Maintenance outages in three-phase power systems where reliable, fast interruption is essential
• Retrofits or replacements in legacy panels that require exact LM3800L specifications
• New installations or panel upgrades in industrial settings needing robust 800A, 3-pole, 600V protection

Important note: Confirm fit and ratings before ordering. The part number is the best reference for compatibility, so match LM3800L with your panel catalog or electrical drawings to ensure a seamless fit.

Installation and compatibility tips

Before replacement or installation, verify that your equipment’s bus rating, mounting style, and termination arrangements align with the LM3800L. Since compatibility hinges on the exact part number, cross-check LM3800L against your panel’s documentation. For safe handling, de-energize systems and follow standard lockout/tagout procedures during installation.

Practical guidance and care

• Store spares in a clean, dry environment to preserve performance
• Periodically inspect the mechanism and terminal connections for signs of wear or loosening
• Maintain accurate asset records by noting the LM3800L part number in your equipment inventory

Designed for reliability in industrial power distribution, the LM3800L 800A 3-Pole 600V breaker offers precise protection, straightforward compatibility, and the resilience you need when your facilities demand uninterrupted, safe operation.
