Westinghouse | HMA3800 | Circuit Breaker | 800A | 3-Pole | 600V

Westinghouse HMA3800 Circuit Breaker is an OEM-grade protection device built for demanding industrial environments. With an 800A rating, a 3-pole configuration, and a 600V operating voltage, it’s specifically designed for maintenance, retrofit, and replacement projects where exact specifications matter.

Why this exact model matters

• Precise compatibility: The part number HMA3800 is the best reference for matching your existing equipment. Confirm fit and ratings before ordering to ensure a seamless swap.
• Three-phase protection: 3-Pole design provides balanced protection for three-phase circuits, helping protect motors, feeders, and heavy loads from faults.
• High-load capacity: 800A rating accommodates demanding industrial feeders and high-current applications without oversizing the protection device.
• Standard industrial voltage: 600V rating aligns with common industrial power distribution, enabling reliable protection in commercial and manufacturing settings.
• OEM reliability for retrofits and replacements: Westinghouse engineering and design deliver predictable performance when extending or modernizing existing panels.

Ideal use cases

• Retrofit projects in commercial or industrial facilities where legacy panels require upgrading to 800A, 3-Pole, 600V protection.
• Maintenance replacements to restore dedicated protection for high-demand feeders and motor circuits.
• Panel and distribution upgrades in manufacturing lines, processing plants, or utility rooms that rely on robust three-phase protection.
• Service vehicles and on-site spares for rapid field repairs, minimizing downtime during critical outages.

Practical guidance for ordering and installation

Before purchasing, verify that the application fits the 800A, 3-Pole, 600V specifications and that the HMA3800 part number matches the required compatibility reference for your panel or distribution gear. This targeted approach helps ensure a secure fit, reliable operation, and smooth integration into your existing electrical system.
