The CE3150B – Federal Pioneer 3P150A 600V 14kA Breaker is a reliable circuit protection solution for your electrical systems. With its three-pole configuration and 150 amp rating, it ensures optimal performance and safety. Designed for 600V applications, this breaker meets high current requirements, offering peace of mind and durability.
Federal Pioneer as a brand was discontinued, making CE-frame breakers like the CE3150B increasingly hard to find through standard supply channels. Northern Breaker Group specializes in obsolete and hard-to-find breakers, so we maintain stock of legacy Federal Pioneer equipment. Contact us for current availability.
The CE3150B can serve as either a feeder breaker or a main breaker, depending on your panelboard's design and the application requirements. Its 150A, 3-pole, 600V bolt-on configuration is well suited for feeder protection in commercial and industrial distribution. Always verify with your panel manufacturer's specifications and consult a licensed electrician to confirm the correct application.
The 14kA interrupting rating means the CE3150B can safely clear fault currents up to 14,000 amperes at 600V without damage. Whether this is sufficient depends on the available fault current (AFC) at your installation point — a value determined by your utility and system impedance. A licensed electrician or engineer should perform a short-circuit study to confirm the breaker's rating meets or exceeds the AFC at your panel.
