Square D BD Series Circuit Breaker Information
Square D BD Series Circuit Breaker Information
The “B” Series BDA Circuit Breaker is Manufactured by Square D to Replace the Obsolete Type FA Circuit Breakers.
Here is an image of the NEW Square D BD
Frame I-Line Circuit Breaker
The BGA and the BJA Frame look identical with the exception of the label depicting the specifications The Dimensions are the same as the FA Circuit Breaker
These are Both I-Line Series and will properly fit in into I-Line Type Panelboards. They both mount the same way and take up the same amount of space in the panel. Also the Plug-In Jaw is the same.
For your Information, you can see the Crown that slides onto the busbar is the same as the FA Series
The BDA Series will always be offered by any knowledgeable Distributor that specializes in Circuit Breakers. If the new series is not offered, I would suggest finding a New Supplier. If you are offered to previous series FA Reconditioned, it is not likely to have had any of the important components cleaned, lubricated and inspected. This is because the FA series Breaker is riveted shut. To Open the case, the rivets must be drilled out, the pieces that surround the rivet must be removed just to see the internal components. At that time you still need to clear the inside of dirt, dust and anything that may have made it into the case. Then you still need to clean the stationary and moveable contacts, lubricate the pivot points and secure the case shut. Although there may be some companies that actually do this, most do not.
