The Square D BGA36110 is a 3 Pole thermal magnetic molded case circuit breaker with a current rating of 110 Amps and a voltage rating of 600Y/347VAC. It has an interrupting rating of 65kAIC at 240VAC, 35kAIC at 480VAC. The BGA36110 has an I-Line mounting type and includes long time and instantaneous trip functions.
Can the PowerPacT BGA36110 replace older Square D circuit breakers?
Yes, the PowerPacT B-frame series is the modern replacement for legacy Square D FA and FH series I-Line circuit breakers. It fits into the same mounting space to ease retrofits and upgrades in existing panels.
What does the 600Y/347VAC rating mean for this breaker?
The slash voltage rating indicates this breaker is suitable only for solidly grounded wye systems up to 600V. It is not rated for use on ungrounded or corner-grounded delta systems at 600V.
How are the line and load connections made on the BGA36110?
The line side features a shrouded I-Line plug-on jaw that connects directly to the panelboard bus. The load side uses factory-installed mechanical lugs that accept 14 to 2/0 AWG aluminum or copper wire.
What do the letters in the BGA36110 catalog number signify?
In the PowerPacT nomenclature, "B" stands for the B-frame size. The "G" indicates the interrupting rating tier (65kA at 240V, 35kA at 480V), and the "A" designates the I-Line plug-on mounting style.
Can I install this breaker in a standard QO or NQ panelboard?
No, the BGA36110 is an I-Line molded case circuit breaker. It is exclusively designed for Square D I-Line panelboards and switchboards and will not fit in QO, NQ, or NF series panels.
Is the trip unit on the BGA36110 adjustable?
No, this breaker features a fixed thermal-magnetic trip unit. Both the long-time overload (thermal) and instantaneous short-circuit (magnetic) trip settings are factory-set and cannot be adjusted in the field.
