Square D BGA36040 – Frequently Asked Questions

1) Will a Square D BGA PowerPacT B breaker mount in my existing I-Line panelboard or switchboard?
Yes, if the bus is Square D I-Line. The BGA uses an I-Line line-side connection that plugs directly onto the I-Line bus stabs, with lugs on the load side for outgoing conductors. It is built for I-Line switchboard and panelboard distribution, so it is not a unit-mount or bolt-on breaker for a standard load center.
2) Can I use a BGA36030 on a 480V system?
No. The BGA family is rated 0Y/347VAC, meaning it is intended for 347V AC (grounded wye, 600/347V systems typical in Canada) and single-phase-to-neutral use on that system, not a 480V three-phase application. If your system is 480Y/277V or straight 480V delta, you need a breaker rated for that voltage instead.
3) What interrupting rating does the PowerPacT B BGA have, and is it enough for my available fault current?
The BGA carries an Ics of 18kA at 500 to 525V AC per IEC 60947-2, with Ue of 525V AC 50/60Hz under UL 489. Compare that 18kA figure against the available short-circuit current calculated at your panel location; if your study shows more than 18kA at that bus, this frame is not the right choice.
4) What wire size can I land on the load lugs of a Square D BGA breaker?
The load lugs accept AWG 14 through 2/0, aluminum or copper. Torque the terminals to 3.6 to 4.4 N.m for AWG 14 through 10, and 5 to 6.2 N.m for AWG 8 through 2/0. That range covers the full 15A to 125A lineup, so a 125A unit still lands 2/0 as its largest conductor.
5) Is an ABB ST200M miniature circuit breaker an alternative to the Square D BGA PowerPacT B for branch circuit protection?
They serve different roles. The Square D BGA PowerPacT B is a UL 489 listed 3-pole breaker covering 15A through 125A for panelboard and switchboard branch and feeder protection. The ABB ST200M is a miniature circuit breaker with a C-curve rated to UL 1077, which is a supplementary protector standard rather than a branch-circuit protective device standard. For a code-compliant branch circuit breaker in a distribution panel, the UL 489 device is the one to specify.
6) Can an ABB A2A150TT molded case breaker replace a Square D BGA PowerPacT B breaker in an I-Line switchboard?
No. The Square D BGA PowerPacT B-Frame breaker uses an I-Line connection on the line side, which is the bolt-on interface specific to Square D I-Line panelboards and switchboards. The ABB A2A150TT is a 3-pole molded case breaker in ABB's A2 series and is not built for that I-Line mounting interface. If the enclosure is an I-Line bussed panel, stay with the BGA; the ABB unit suits its own frame-mounted or lug-connected applications.
7) What is the closest thermal magnetic 3-pole alternative to the Square D BGA PowerPacT B if I am not tied to an I-Line panel?
The ABB E150 series 3-pole thermal magnetic circuit breaker is the nearest match in operating principle and pole count. Both are 3-pole thermal magnetic devices for distribution duty. The difference is the mounting and connection: the Square D BGA is built with an I-Line line connection for Square D bussed panelboards and switchboards, so the ABB E150 applies where the panel does not require that I-Line interface.
8) Which amp ratings are available in the BGA 3-pole I-Line breaker, and what are the part numbers?
Twelve Motor FLA ratings: 15A (BGA36015), 20A (BGA36020), 25A (BGA36025), 30A (BGA36030), 40A (BGA36040), 50A (BGA36050), 60A (BGA36060), 70A (BGA36070), 80A (BGA36080), 90A (BGA36090), 100A (BGA36100) and 125A (BGA36125). All share the same 3-pole frame, 347VAC rating and I-Line connection, so sizing up or down within the family does not change the panel interface.
9) Is the BGA acceptable for a rooftop air conditioning unit circuit?
Yes, the BGA is HACR rated, which is what an inspector looks for on a branch circuit feeding air conditioning or refrigeration equipment. It is a thermal magnetic 3-pole device sized by Motor FLA from 15A to 125A, so match the breaker to the nameplate FLA and minimum circuit ampacity on the unit.
10) Does the BGA PowerPacT breaker have an electronic trip unit or a fixed thermal magnetic trip?
Fixed thermal magnetic. The BGA uses a thermal magnetic trip with a toggle operating handle and is suitable for isolation per IEC 60947-2. There are no adjustable electronic trip settings, so the protection is determined by the FLA rating you order rather than field programming. Note also that the unit is listed as non-serviceable, so a tripped-and-failed breaker is replaced, not rebuilt.
11) What standards and certifications does the Square D BGA breaker carry for a spec submittal?
UL 489 Listed, CSA C22.2 No. 5, NEMA AB1, EN/IEC 60947-2 and 60947-5-1, GB 14048.2 and NMX J-266. Product certifications on record are UL, NOM, CCC, EAC, IEC and CSA, with a CE quality label. That covers the usual North American commercial and industrial submittal requirements for a molded case distribution breaker.
12) What are my options if my panel is not Square D I-Line?
An I-Line connection breaker only plugs onto Square D I-Line bus, so on other gear you need a breaker matched to that manufacturer's mounting. For 3-pole molded case alternatives on the ABB side, ZenSupply carries the ABB A2A150TT in the A2 Series, the ABB E150 Series 3-pole thermal magnetic breaker, and the ABB XT4 Series 3-pole kit. Confirm the voltage and interrupting rating against your system before substituting, since those differ by family.
13) I was quoted an ABB XT4 kit instead of a Square D BGA breaker - are those the same thing?
No. The ABB MBB33 is an XT4 series 3-pole molded case circuit breaker kit, so it is supplied as a kit within ABB's XT4 frame. The Square D BGA PowerPacT B-Frame is a complete 3-pole thermal magnetic breaker rated 347VAC with an I-Line line connection and load lugs, ordered by Motor FLA rating from BGA36015 at 15A up to BGA36125 at 125A. Confirm the frame and connection your panel requires before accepting the swap.
14) Can these breakers be installed in an unheated mechanical room or outdoor enclosure?
The BGA is rated for an ambient operating range of -25C to 70C, which covers unconditioned mechanical spaces and cold climates. The front cover degree of protection is IP40, so it needs to sit inside a suitably rated enclosure for any wet or outdoor location. The breaker itself is not a weatherproof device.
15) How many operations will a PowerPacT B BGA breaker take if it is switched daily?
Endurance is 20,000 mechanical cycles and 10,000 electrical cycles per IEC 947-1 Annex K. For a breaker being used as a daily on/off switch rather than purely as overcurrent protection, the 10,000 electrical figure is the one that governs service life.
16) Are Square D PowerPacT BGA breakers mercury free and RoHS compliant for a green building submittal?
Yes. The BGA is a Green Premium product, halogen-free and mercury-free, and in scope for European RoHS. Packaging is noted as sustainable and uses recycled cardboard, which helps on projects tracking material and waste credits.
