The NB3P15 – Federal Pioneer 3P15A 120/240V Bolt On 10kA Breaker is a reliable solution for your electrical system needs. Designed for durability and optimal performance, this three-pole circuit breaker is rated for 15 amps, offering 10kA short-circuit protection. Ideal for residential and commercial applications, it ensures safety and efficiency.
The NB3P15 is designed for Federal Pioneer Stab-Lok panelboards that accept NB-series bolt-on breakers. Because Stab-Lok panels came in several configurations, we recommend sending us your panel model number so we can confirm the NB3P15 is the correct fit before you purchase.
Federal Pioneer breakers are no longer manufactured under that brand, making the NB3P15 a hard-to-find, obsolete part. Northern Breaker Group specializes in sourcing exactly these discontinued and legacy breakers — contact our Calgary, Edmonton, or Vancouver branches or request a quote online and we'll check current stock availability for you.
The 10kA (10,000 ampere) interrupting rating is the maximum fault current the NB3P15 can safely clear without damage. For most residential and light commercial services in Canada, 10kA is adequate, but you should verify the available short-circuit current at your panel against this rating. If your service has a higher fault-current level, a higher-kA rated breaker would be required — our team can help you assess this.
