The EJB26045 SQUARE D 2P 45A 600/347V circuit breaker is a reliable solution for managing electrical loads in both commercial and residential applications. Designed for two-pole systems, it offers durability and performance with a current rating of 45 amps. Perfect for safeguarding circuits while ensuring efficient operation in your electrical setup.
The EJB26045 is a molded-case circuit breaker (MCCB) rated for 600/347V with a 25kA interrupting capacity, designed for commercial and industrial panelboards and switchboards. Square D QO and Homeline breakers are residential-grade plug-in or bolt-on breakers rated for 120/240V loadcentres. The EJB frame is a heavier-duty product class intended for higher-voltage, higher-fault-current environments.
Square D's EJB frame series has seen limited availability as product lines evolve. Northern Breaker Group specializes in sourcing obsolete and hard-to-find breakers across Canada. Whether new, reconditioned, or surplus stock, contact our Calgary, Edmonton, or Vancouver counters and we'll work to locate the EJB26045 for you.
Yes, the EJB26045 at 45A/600V is commonly applied to motor branch-circuit and feeder protection in commercial installations. However, motor circuit sizing must comply with the Canadian Electrical Code (CEC), which prescribes specific maximum overcurrent device ratings based on motor FLA and type. We recommend confirming your motor's nameplate data and consulting a licensed electrician or engineer to ensure code compliance.
