Square D BGA24100Y1 – Frequently Asked Questions

1) Will the Square D PowerPacT B-Frame BGA breaker mount in an I-Line panelboard?
Yes. The PowerPacT B-Frame 2-pole BGA breaker uses an I-Line connection on the line side, so it plugs onto I-Line bus stabs, with lug connections on the load side. That makes it a drop-in for I-Line panelboard distribution rather than a bolt-on or plug-on load center breaker.
2) What amp ratings does the Square D BGA 2-pole PowerPacT B breaker come in?
Two Motor FLA ratings are offered on the 2-pole BGA breaker: 30A (BGA260301) and 100A (BGA24100Y1). The published range is 30A to 100A, so if your branch circuit or motor load falls between those two values you need to pick the rating that matches the load, not an intermediate trip setting - this is a fixed thermal magnetic breaker, not an adjustable electronic trip unit.
3) Can I use this breaker on a 480V or 600V three-phase system?
The BGA 2-pole PowerPacT B breaker is rated 600Y/347VAC, which covers 480Y/277V and 600Y/347V wye-connected systems. Its UL 489 rated operational voltage is listed as Ue 525V AC 50/60Hz. Note the Y rating: it is intended for solidly grounded wye systems, so a 600V delta or corner-grounded delta service is outside what is published for it.
4) Is 18kA enough interrupting capacity for my panel?
The BGA 2-pole breaker carries an 18kA interrupting rating (Ics), stated at 500-525V AC per IEC 60947-2. Compare that against the available fault current at the panelboard from your utility or coordination study. If your calculated fault current at that point exceeds 18kA and you have no upstream series rating or current-limiting fuse to back it up, you need a higher AIC frame instead.
5) Can I use an ABB ST200M miniature circuit breaker instead of the Square D PowerPacT B breaker?
No. The ABB ST200M is a C-curve miniature circuit breaker listed to UL 1077, which is a supplementary protector standard. The Square D PowerPacT B BGA is UL 489 listed, which is the standard for branch-circuit protection. If the drawing calls for branch-circuit or feeder protection, the UL 489 device is required; a UL 1077 supplementary protector cannot take its place.
6) I need a 3-pole breaker instead of the Square D PowerPacT B 2-pole - what are the options?
The Square D PowerPacT B BGA breaker is a 2-pole configuration only. For three-pole molded case protection, the ABB XT4 Series 3-pole molded case circuit breaker kit and the ABB XT5 3-pole circuit breaker kit are both 3-pole molded case devices, and the ABB A2A150TT is a 3-pole molded case breaker in the A2 Series. Confirm the panelboard mounting system before ordering, since the PowerPacT B uses an I-Line connection.
7) What is the difference between the Square D PowerPacT B breaker and an Eaton BAB Quicklag breaker?
The Square D PowerPacT B BGA is a 2-pole thermal magnetic breaker rated 600Y/347VAC with an I-Line connection for panelboard bus mounting. The Eaton BAB Quicklag industrial thermal-magnetic breaker is a 240V, three-pole bolt-on style device. Both are thermal-magnetic, but the voltage class and the mounting method are different, so the BAB suits 240V bolt-on panel applications while the PowerPacT B covers 600Y/347VAC I-Line distribution.
8) What wire size and torque does the load side lug on this PowerPacT B breaker take?
The load lugs accept AWG 14 through AWG 2/0, aluminum or copper. Tighten to 3.6-4.4 N.m for AWG 14-10 and 5-6.2 N.m for AWG 8-2/0. At the 100A rating you will be at the upper end of that range, so plan conductor size accordingly before you pull wire.
9) Is this breaker approved for HVAC equipment and rooftop units?
Yes. The PowerPacT B-Frame BGA breaker is HACR rated and UL 489 listed, which is what inspectors look for when a breaker feeds heating, air conditioning and refrigeration equipment. It also carries CSA C22.2 No. 5, NEMA AB1 and EN/IEC 60947-2 compliance for projects that call for Canadian or international listings.
10) Thermal magnetic or electronic trip - which do I need for a motor feeder?
This BGA breaker is thermal magnetic, meaning fixed overload and short-circuit response with no adjustable pickup or time delay. For a standard motor branch circuit or feeder inside the 30A to 100A range that is normally all that is required, and it is the simpler and smaller option. Where you need adjustable long-time, short-time or ground-fault settings for selective coordination with downstream devices, an electronic trip unit frame is the better choice.
11) What else could I use instead of a Square D PowerPacT B 2-pole molded case breaker?
If the opening is not an I-Line panelboard, the alternatives are different in how they connect. ABB's A2A150TT is a 3-pole molded case breaker in the A2 Series, and ABB offers 3-pole kits in the XT4 and XT5 series. For bolt-on branch breaker applications rather than molded case, Eaton's BAB Quicklag thermal-magnetic line includes bolt-on 2-pole and 3-pole devices. None of those will land on an I-Line bus, so the choice follows the panel you are feeding, not just the amp rating.
12) I need a 3-pole breaker for a three-phase load. Does the BGA cover that?
The BGA breaker described here is a 2-pole AB frame device. For a three-phase load you need a 3-pole breaker. Among other brands we carry, the ABB A2A150TT is a 3-pole molded case breaker and the ABB XT4 and XT5 kits are 3-pole, and Eaton's BAB-302 Quicklag is a three-pole 240V thermal-magnetic unit. Match the connection method to your panel before you order.
13) The Square D PowerPacT B tops out at 100A motor FLA - what should I look at for a larger frame?
The PowerPacT B BGA breaker covers a 30A to 100A amperage range in a 2-pole build. For a substantially larger frame, the Eaton Series C K-Frame mining circuit breaker is a 400A 3-pole device with an interchangeable rating plug. Note the pole count and mounting differ from the I-Line 2-pole PowerPacT B, so verify the panel and the application before specifying it.
14) How many operations will this breaker take if it gets switched regularly?
Rated life on the BGA 2-pole breaker is 20,000 mechanical operating cycles and 10,000 electrical cycles per IEC 947-1 Annex K. That is adequate for routine maintenance switching in a distribution panel. For an application where the breaker is being used as a frequent on/off disconnect for process equipment, a contactor or motor starter ahead of it is the better way to absorb the cycling.
15) What is the enclosure protection rating and color on the Square D PowerPacT B BGA breaker?
Housing is gray, RAL 7016, with IP40 degree of protection on the front cover. IP40 means it is protected against solid objects over 1mm but has no water ingress rating, so it needs to live inside a panelboard or a suitably rated enclosure rather than in the open.
16) What insulation and impulse withstand voltage does this breaker hold for control panel builds?
Rated insulation voltage (Ui) is 800V and rated impulse withstand voltage (Uimp) is 8kV per IEC 60947-2. Those are the numbers an OEM panel builder needs for clearance and creepage calculations and for IEC-referenced panel documentation.
17) Does the Square D PowerPacT B BGA breaker include an undervoltage release like the Eaton NZM accessory?
No. The PowerPacT B BGA is a thermal magnetic breaker with a thermal magnetic trip for overload and short-circuit response, supplied as the breaker itself. The Eaton 10250T Series item is an undervoltage release accessory for NZM Series molded case breakers, not a breaker, and it is built for the NZM frame rather than the PowerPacT B.
