The NA250 – Federal Pioneer 2P50A 120/240V Push In Breaker offers dependable protection for your electrical circuits. With a rating of 50 Amps and a breaking capacity of 10kA, this two-pole breaker is designed for easy installation and reliable performance. Ideal for residential and light commercial applications. Ensure safety with this essential component.
The NA250 is a plug-in breaker from Federal Pioneer's NA series, compatible with Federal Pioneer Stab-Lok loadcentres and panelboards designed to accept NA-frame push-in breakers. Because Stab-Lok is a legacy product line with several panel generations, we recommend providing your panel's model number so we can confirm compatibility before purchase.
Federal Pioneer (and the Stab-Lok line) has been discontinued for many years, making NA-series breakers a hard-to-find, obsolete part. Northern Breaker Group specializes in sourcing exactly these kinds of legacy breakers — contact us for availability and a quote, as stock is limited.
Stab-Lok breakers use a proprietary plug-in design, and only breakers specifically listed for Federal Pioneer Stab-Lok panels should be installed. Substituting an unlisted breaker from another brand is not code-compliant and can create a safety hazard. We can help you source a genuine NA250 or a listed equivalent — reach out to our team for guidance.
