Product FAQs
6 answersWhat type of panelboards accept the BGA34020Y circuit breaker?
This breaker is designed exclusively for Square D I-Line panelboards and switchboards. It features a plug-on I-Line connection for the line side and lug terminals for the load side.
Can I use the BGA34020Y to replace an older FA or FH frame I-Line breaker?
Yes, Square D PowerPacT B-frame breakers are the direct replacement for legacy FA and FH frame I-Line breakers. They fit into the same mounting space, making retrofits and panel expansions straightforward.
How does the I-Line connection mount into the panelboard?
The breaker snaps directly onto the panel's I-Line bus stack using plug-on jaws on the line side. This allows for quick installation without requiring individual mounting hardware or cable connections on the line side.
Is the BGA34020Y suitable for use on direct current (DC) circuits?
Yes, this breaker is rated for up to 250VDC with an interrupting capacity of 20kA, making it suitable for specific DC applications.
What wire sizes and materials are compatible with the load lugs on this breaker?
The factory-installed load lugs accept 14 AWG to 2/0 AWG wire and are compatible with both aluminum and copper conductors.
What type of protection does the thermal-magnetic trip unit provide?
The fixed thermal-magnetic trip unit provides standard LI protection, which includes Long-Time (L) sensing for overloads and Instantaneous (I) sensing for short circuits.
