The Square D EDB26045 is a bolt-on, 2-pole 45A 600/347V molded-case circuit breaker from Square D's EDB frame. As an MCCB rated at 600V/14kA, it is designed for commercial and industrial panelboards and switchboards — not residential loadcentres. It is typically used in Square D NF, I-Line, and compatible commercial panelboard enclosures that accept EDB-frame bolt-on breakers.

No, they cannot be interchanged. The EDB is a commercial/industrial molded-case circuit breaker (MCCB) rated up to 600V, designed for bolt-on mounting in commercial panelboards and switchboards. QO and Homeline are residential-grade plug-on breakers for their respective loadcentres. Different mounting methods, voltage ratings, and enclosures mean these frames are not cross-compatible.
Yes — the EDB26045 carries a dual voltage rating of 600V AC (suitable for 3-phase systems) and 347V AC (commonly used in Canadian 600Y/347V distribution systems for lighting and branch circuits). As a 2-pole breaker, it is well-suited for 347V single-phase branch protection or as part of a 600V system. Confirm your system voltage and configuration with our team if you have any questions.
