Product FAQs
8 answersWhat panels are compatible with the BGA160203 circuit breaker?
This breaker is designed exclusively for use in Square D I-Line panelboards and switchboards.
Can the BGA160203 replace older Square D circuit breakers?
Yes, the PowerPacT B-frame series is the designated modern replacement for legacy Square D FA and FH series I-Line circuit breakers. It maintains the same mounting space dimensions to easily retrofit into existing panels.
What wire sizes and materials do the lugs on the BGA160203 accept?
The factory-installed lugs on this breaker accept 14 AWG to 2/0 AWG wire, and are compatible with both aluminum and copper conductors.
What does the G in the BGA160203 part number signify?
The G indicates the breaker's interrupting rating tier. For this model, it provides a maximum interrupting capacity of 65 kA at 240VAC, 35 kA at 480VAC, and 18 kA at 600Y/347VAC.
How is the BGA160203 installed into a panel?
It utilizes the Square D I-Line plug-in mounting system. The breaker's jaws plug directly into the panel's busbar stack, and it is then secured to the panelboard using a captive mounting screw.
Is the BGA160203 suitable for direct current (DC) systems?
Yes, this breaker is rated for use in DC applications up to 125VDC, with a DC interrupting rating of 20 kA.
Are the trip settings adjustable on the BGA160203?
No, this breaker features a fixed thermal-magnetic trip unit. The long-time (overload) and instantaneous (short circuit) trip thresholds are factory set and cannot be adjusted in the field.
What does the 600Y/347VAC voltage rating mean for this breaker?
The 600Y/347VAC slash rating indicates this breaker is approved for use on solidly grounded Wye systems up to 600V, where the voltage to ground does not exceed 347V.
