Meet the Westinghouse LM3800 Circuit Breaker — a purpose-built solution for demanding electrical systems that demand dependable overcurrent protection. This 800A, 3-pole unit is engineered for bolt-on mounting, delivering secure, durable performance in maintenance, retrofit, and replacement projects where exact specifications matter.

• Amperage rating: 800 A
• Poles: 3-Pole (three-phase protection)
• Voltage rating: 600 V
• Mounting: Bolt-On — a robust, screw-tight connection for reliable service in compatible panels
• Compatibility reference: The part number LM3800 is the best reference for ensuring fit and ratings—confirm compatibility before ordering

The LM3800 isn’t just about numbers — it’s about steady protection when it matters most. With its three-pole design, you get balanced, synchronized interruption across all phases, helping preserve equipment and reduce downtime. The bolt-on installation simplifies panel retrofits and replacements, enabling quicker service calls and less downtime during upgrades.

Ideal use cases:

• Maintenance and replacement of existing three-phase systems that require an 800A, 600V bolt-on breaker
• Retrofits in industrial panels, commercial power distribution rooms, and service equipment needing higher current protection
• Upgrades to ensure reliability in high-demand motor loads, feeders, and panelboard circuits

Why this Westinghouse model stands out — precise amperage with a straightforward bolt-on installation translates to faster replacements, clearer asset tracking (via LM3800 as the primary reference), and dependable performance in service-grade environments. By aligning with your panel’s specs, it minimizes compatibility risk and supports long-term operational continuity.

Practical tips for a smooth upgrade — before you order, verify that your panel is designed for bolt-on LM3800-type breakers and that the LM3800’s 800A, 3-Pole, 600V ratings match your protection requirements. Keep the part number handy (LM3800) to confirm the exact fit with your equipment and to simplify procurement and future maintenance.
