Product FAQs
6 answersCan the BGA34070Y replace older Square D 70A breakers?
Yes, this PowerPacT B-Frame breaker is a direct upgrade for legacy FA and FH frame breakers, such as the FA34070 or FH34070. It fits into the same I-Line panelboards and retains the ABC phase connection.
How are the line and load connections configured on this breaker?
The line side (ON end) utilizes a shrouded I-Line plug-on jaw for direct bus connection, while the load side (OFF end) features factory-installed mechanical lugs that accept 14 to 2/0 AWG aluminum or copper wire.
What does the Y suffix indicate in the BGA34070Y part number?
The Y suffix designates that this 3-pole I-Line breaker is factory-configured with a standard ABC phase connection.
How can I manually test the mechanical operation of the BGA34070Y?
PowerPacT B-Frame breakers feature an integral push-to-trip button on the front cover, allowing you to manually trip the breaker to verify the mechanical linkage is functioning properly before or after installation.
Is the BGA34070Y rated for 100 percent continuous duty?
No, this breaker carries a standard 80 percent continuous current rating.
What type of fault protection does the BGA34070Y provide?
It is equipped with a fixed thermal-magnetic trip unit for Long-Time and Instantaneous (LI) protection. The breaker also utilizes dual-break rotating contacts designed to limit peak current and let-through energy during a short circuit fault.
