Federal Pioneer NB20 - 20 A, 120 V, 1-Pole Bolt-On Circuit Breaker | AmpState

Introducing the Federal Pioneer NB20— a 20A, 120V, 1-pole bolt-on molded case circuit breaker designed to protect branch circuits in panelboards and loadcenters. Built for dependable overcurrent and short-circuit protection, it’s a reliable choice for modern electrical installations in homes, offices, and light-industrial spaces.

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection that stays solid through temperatures and vibrations common in busy electrical panels.
• Thermal-magnetic trip unit delivers stable, repeatable protection by quickly responding to overloads and short circuits while minimizing nuisance trips.
• OEM-compatible design ensures seamless integration with matching Federal Pioneer, or OEM-load centers and panelboards for a clean, code-compliant installation.
• Versatile applications suited for residential, commercial, and light industrial circuits, including branch circuits that require reliable 20A protection at 120V.
