Federal Pacific NB125 - 125A, 2-Pole, Circuit Breaker

Meet the Federal Pacific NB125 — a rugged 125A, 2‑Pole circuit breaker built to deliver dependable overcurrent protection where it matters most. Designed to integrate seamlessly with panelboards, switchboards, and control panels, this device keeps critical distribution systems safe and operating smoothly in demanding environments.

Why the NB125 stands out:

• 125 Ampere rating provides solid protection for feeders and branch circuits in industrial facilities, commercial spaces, and OEM panels without compromising performance.
• 2‑Pole configuration ensures coordinated protection across two conductors, improving fault clarity and reducing arc risk in multi‑wire circuits.
• Versatile integration compatible with panelboards, switchboards, and motor control centers, making it an ideal choice for both new installations and retrofits.
• Industrial-grade reliability designed to support safe operation in distribution panels and control panels where continuous, dependable protection is critical.

Ideal use cases include safeguarding motor feeders in motor control centers, protecting large branch circuits in commercial electrical rooms, and serving as a robust, OEM-ready component for custom control panel builds. If your goal is consistent overcurrent protection that you can trust in critical applications, the NB125 is engineered to deliver.

Who should consider this breaker? electricians, controls engineers, and OEM integrators working in environments where reliable interruption of fault currents matters—and where 125A, 2‑pole protection in panelboards, switchboards, or control panels is required for safe, efficient operation.

Practical tips for maximizing performance:

• Match the NB125 to compatible panelboard or switchboard configurations that support 2‑pole 125A protection for straightforward installation.
• Plan for coordinated protection across related circuits in motor control centers to simplify fault diagnosis and maintenance.
• Verify mounting and wiring clearances in your distribution layout to ensure optimal clearance and accessibility for testing and resets.
