CEJ3125E – FEDERAL PIONEER 3P125A 240V 10kA BREAKER
The CEJ3125E – Federal Pioneer 3P125A 240V 10kA Breaker is a reliable and robust circuit breaker designed for heavy-duty applications. With a three-pole configuration and a 125 amp rating, it provides excellent protection for your electrical systems. Ideal for residential and commercial use, ensuring safety and stability in powering your equipment.
The CEJ3125E is a bolt-on MCCB from Federal Pioneer's CEJ frame series, intended for Federal Pioneer commercial panelboards and switchboards designed to accept CEJ-frame breakers. It is not a Stab-Lok plug-in breaker and will not fit standard Federal Pioneer residential Stab-Lok loadcentres. If you're unsure whether your panel accepts this frame, send us your panel model number and we'll confirm compatibility.
Federal Pioneer is a legacy brand and many of its MCCB lines, including the CEJ series, are discontinued or difficult to source through conventional channels. Northern Breaker Group specialises in obsolete and hard-to-find breakers like this one. Contact us or visit one of our Calgary, Edmonton, or Vancouver counters for current availability — we recommend requesting a quote as stock of legacy units is limited.
Yes — a 3-pole, 125A bolt-on MCCB like the CEJ3125E is commonly used as a main disconnect or sub-feed breaker in compatible commercial panelboards, providing branch-circuit protection at up to 240V with a 10kA interrupting rating. Its suitability for a specific application will depend on your panel's bus rating, available spaces, and local electrical code requirements (CEC). We recommend consulting a licensed electrician to confirm the installation meets code.
