Engineered for heavy-duty electrical protection, the Westinghouse NB3800PRF Circuit Breaker delivers reliable 800A, three-pole performance at 600V with a bolt-on mounting design. This unit is purpose-built for maintenance, retrofit, and replacement projects where exact specifications matter—and where minimizing downtime is critical. If your panel requires a precise NB3800PRF fit, this breaker offers a straightforward path to restore, upgrade, or expand service capacity without unnecessary complexity.

Key specifications and compatibility

  • Amperage: 800 A
  • Poles: 3-Pole
  • Voltage: 600 V
  • Mounting: Bolt-On
  • Compatibility reference: The part number NB3800PRF is the best reference for compatibility—confirm fit and ratings before ordering.

What makes this breaker stand out

  • Bolt-On convenience: A robust bolt-on design supports rapid installation and secure mounting in compatible panels, reducing service downtime during replacements or retrofits.
  • High-current capacity: At 800A, it’s suited for demanding industrial and commercial applications that demand strong overcurrent protection for sizable loads.
  • Clear reference for compatibility: Rely on the NB3800PRF part number as your primary guide to ensure exact matching specifications in your panel configuration.

Ideal use cases

  • Electrical service upgrades or panel refurbishments where a precise 800A, 3-Pole, 600V bolt-on breaker is required.
  • Maintenance spares for industrial control panels, manufacturing lines, and distribution panels needing dependable replacement parts.
  • Retrofit projects that modernize protection schemes while preserving existing wiring and bus configurations.

Installation tips and practical considerations

  • Before ordering, verify that your panel enclosure supports bolt-on breakers and that the bus configuration matches the NB3800PRF design.
  • Cross-check the panel’s labeling and documentation to confirm amperage, voltage, and three-pole protection requirements align with 800A, 600V, and 3-Pole specifications.
  • During replacement or retrofit, de-energize the system, follow lockout/tagout procedures, and use the correct mounting hardware to ensure a secure hold and proper electrical contact.
  • Keep a spare NB3800PRF on hand for routine maintenance cycles or unexpected replacements to minimize downtime.
