Square D BDA160205 – Frequently Asked Questions

1) Will a Square D PowerPacT B breaker mount in an I-Line panelboard?
Yes. The PowerPacT B-Frame breakers use an I-Line connection on the line side, so they plug directly onto the I-Line bus stabs in a Square D I-Line panelboard. The load side is lugs, which you wire out to the branch conductors. If your panel is a bolt-on or plug-in load center rather than I-Line, this connection style will not seat.
2) What amp ratings and pole counts does the Square D PowerPacT B thermal magnetic breaker come in?
Pole counts are 1-pole and 3-pole. The 1-pole units cover 20A (BDA160205) and 60A (BDA140603). The 3-pole units run 15, 20, 25, 30, 35, 40, 50, 60, 70, 80, 90, 100, 110 and 125 amps, with part numbers such as BDA34015Y at 15A, BDA36040 at 40A, BDA34100Y at 100A and BDA36125 at 125A. Order by the exact catalog number for the amp rating you need.
3) Can I use this PowerPacT B breaker on a 347V lighting circuit?
Yes, that is what the 0Y/347VAC rating is for. A 1-pole PowerPacT B at 347VAC suits single-pole 347V distribution, which is common on 480/277 and 600/347 lighting systems in commercial buildings. Interrupting rating is 14kA, so confirm your available fault current at the panel is within that.
4) Can an ABB E150 thermal magnetic breaker be used in place of a Square D PowerPacT B breaker?
Not directly in an I-Line panelboard. The Square D PowerPacT B breaker uses an I-Line connection on the line side, which is a plug-on interface specific to I-Line panelboards, with lugs on the load side. The ABB E150 is a 3-pole thermal magnetic molded case circuit breaker, so it matches the trip technology but is a separate mounting platform. Use it where the enclosure or panel is built for E150 mounting, and stay with the PowerPacT B where the bus is I-Line.
5) What is the difference between a PowerPacT B breaker and an ABB ST200M miniature circuit breaker?
They are different classes of device. The Square D PowerPacT B is a molded case thermal magnetic circuit breaker that is UL Listed to UL 489 for branch circuit and feeder protection in distribution panels. The ABB ST200M is a miniature circuit breaker certified to UL 1077, which is a supplementary protection standard rather than a branch circuit standard. If the drawing calls for branch circuit protection, the UL 489 device is the one to specify.
6) Is the Square D PowerPacT B breaker UL 489 listed, and what other approvals does it carry?
It is UL Listed to UL 489 and CSA certified to CSA C22.2 No. 5, plus NOM, CCC and EAC approvals. It also complies with IEC 60947-2 and IEC 60947-5-1 and the NEMA AB1, GB 14048.2 and NMX J-266 standards, and carries CE marking. That covers most North American inspection requirements and export panel builds on one part number.
7) Thermal magnetic or electronic trip: which should I spec for a distribution panel?
Thermal magnetic, like the PowerPacT B here, uses a bimetal element for overload and a magnetic element for short circuit. Trip settings are fixed by the catalog number, which is why you order the exact amp rating. That is the right choice for straightforward branch distribution and HACR loads. Electronic trip units are what you go to when you need adjustable long-time, short-time or ground-fault settings for selective coordination. For a standard 347V lighting or HVAC feeder, thermal magnetic is the simpler and fully code-compliant answer.
8) What is the front cover protection rating and mounting pitch on the PowerPacT B?
Front cover protection is IP40 per IEC 60529, with a toggle operator and a gray RAL 7016 housing. Connection pitch is 27 mm, equal to three 9 mm pitches, which is what you use to lay out pole spacing and check the space the breaker takes on the bus.
9) Is the ABB XT4 kit a substitute for a PowerPacT B breaker?
No. The ABB MBB33 is an XT4 Series 3-pole molded case circuit breaker kit, meaning it is a mounting or accessory kit tied to the XT4 frame rather than a complete protective device you can drop into an I-Line panelboard. The Square D PowerPacT B is the breaker itself, a 1-pole or 3-pole thermal magnetic device with an I-Line line connection. Order the PowerPacT B when you need the breaker; the XT4 kit only applies to an XT4 installation.
10) For a HACR-rated rooftop unit circuit, does the PowerPacT B or an ABB A2N breaker apply?
The Square D PowerPacT B is HACR rated and 80% rated, so it is intended for heating, air conditioning and refrigeration circuits as well as general distribution, and it covers motor FLA ratings from 15A through 125A in 3-pole. The ABB A2A150TT is an A2 Series 3-pole UL Listed molded case breaker on a different frame. Where the panel is I-Line and the spec calls out HACR, the PowerPacT B matches directly.
11) Can I rebuild or repair a PowerPacT B breaker if it fails?
No. Serviceability is listed as No, so the breaker is a sealed, non-serviceable device. If it fails you replace the unit with the same catalog number. Accessories, auxiliaries and connection options are available separately for the B-Frame, but the breaker itself is not field repairable.
12) Does the PowerPacT B breaker meet green building and RoHS requirements for our spec?
It is a Green Premium product: RoHS compliant with exemptions, halogen free and mercury free, with an environmental disclosure reference of ENVPEP2311047_V2. Packaging is sustainable, made with recycled cardboard and free of single-use plastic. Useful documentation if you are chasing LEED or corporate sustainability credits on a procurement package.
13) How is the PowerPacT B breaker packaged, and can I buy a single unit?
Packaging is 1 each, so breakers are sold and shipped individually by catalog number. For a panel build you order one line per amp rating and pole count, for example BDA36080 for an 80A 3-pole.
