This single-pole breaker features a 50-amp capacity and is ideal for high-voltage applications, ensuring reliable performance and safety. Upgrade your electrical setup with this durable, high-quality component from SQUARE D.
The EJB14050 is a bolt-on molded-case circuit breaker rated for commercial and industrial panelboards and switchboards — not residential loadcentres. It is commonly found in 277V lighting distribution panels. The specific panelboard must be designed to accept Square D EJB-frame bolt-on breakers. Contact us with your panel model and we'll confirm the fit.
The 277V rating makes the EJB14050 ideal for commercial lighting circuits fed from a 480Y/277V three-phase, four-wire distribution system — a very common configuration in commercial and industrial buildings across Canada. It should not be used on systems exceeding its 277V single-pole voltage rating.
The EJB frame series is considered a legacy/obsolete Square D line. Northern Breaker Group specializes in hard-to-find and obsolete breakers and may have new, reconditioned, or surplus stock available. Reach out to our Calgary, Edmonton, or Vancouver counter for availability and lead times.
