Panel Compatibility

The Square D EDB16020 is a bolt-on, single-pole 20A / 347V / 14kA breaker from the EDB (EDB1) frame series — a commercial/industrial molded-case breaker designed for installation in Square D NF, I-Line, and compatible commercial panelboards and switchboards rated for 347V or 600V-class systems. It is not a plug-in residential breaker and is not intended for QO or Homeline loadcentres. Not sure if this breaker fits your panel? Send us your panelboard model and we'll confirm compatibility.

The Square D EDB frame series is rated for use on 347/600V systems, making the EDB16020 well suited for commercial and industrial branch circuits fed from Canadian 600V-class distribution — including 347V single-phase lighting circuits common in commercial buildings. Its 14kA interrupting rating provides solid fault protection for these environments.

Availability of specific EDB-frame breakers can vary. Northern Breaker Group specialises in obsolete and hard-to-find breakers across Canada, with counter locations in Calgary, Edmonton, and Vancouver. Contact us for a quote — we'll check current stock and source options for you.

Not necessarily. The EDB frame is specific to bolt-on commercial panelboards rated for 347/600V; substituting a different frame or a plug-in breaker could compromise the panel's voltage and interrupting-rating integrity. Always match the frame series, voltage rating, and interrupting capacity to the original. If you're unsure, share your panel model with us and we'll recommend the correct replacement.
