The NB270 – Federal Pioneer 2P70A 120/240V Bolt On Circuit Breaker is designed for reliable performance in residential and commercial applications. With a robust 10kA interrupting capacity, this dual pole breaker ensures your electrical system remains safe and efficient. Ideal for various setups, it offers peace of mind for your circuit protection needs.
Federal Pioneer breakers are no longer manufactured under that brand, making the NB270 a hard-to-find item. Northern Breaker Group specializes in obsolete and discontinued Canadian breakers — we maintain stock of Federal Pioneer NB-series units and can source them for you. Contact one of our Calgary, Edmonton, or Vancouver counters or request a quote online.
Federal Pioneer produced two main residential breaker styles: the well-known Stab-Lok plug-in design and a bolt-on design (NB series). The NB270 uses a bolt-on mounting method, meaning it fastens mechanically to the bus bar with hardware rather than snapping on. These two types are NOT interchangeable — always verify which mounting style your panel requires before purchasing.
No — Federal Pioneer NB-series bolt-on breakers are not universally interchangeable with other brands. Canadian Electrical Code (CEC) requires that replacement breakers be approved for use in the specific panelboard. Only a breaker certified as compatible with your Federal Pioneer panel should be installed. Contact us with your panel model and we'll help identify the correct approved replacement.
