Product FAQs
6 answersCan I install the BDA160303 in a standard Square D NQ or NF panelboard?
No, this breaker features an I-Line plug-in mounting style. It is exclusively compatible with Square D I-Line panelboards and switchboards, and will not fit in NQ, NF, QO, or Homeline panels.
What does the 3 at the end of the BDA160303 catalog number indicate?
In the PowerPacT B-Frame I-Line nomenclature, the final digit indicates the phase connection. The 3 signifies that this 1-pole breaker is factory-configured to connect to the B-phase of the panel bus.
Is the BDA160303 a suitable replacement for older FA series breakers?
Yes, this PowerPacT B-Frame breaker acts as an exact, modern substitute for discontinued 30-amp, 1-pole FA17030 circuit breakers used in legacy I-Line panelboards.
Are the trip settings on the BDA160303 adjustable?
No, this breaker is equipped with a fixed thermal-magnetic trip unit. The long-time overload and instantaneous short circuit protection limits are factory-calibrated and cannot be modified in the field.
How are wires terminated on the BDA160303?
The line side connects directly to the panel bus via the I-Line plug-in jaw, while the load side uses mechanical lugs that accept 14 AWG to 2/0 AWG aluminum or copper wiring.
What interrupting rating does the D in BDA160303 represent?
In the Square D PowerPacT B-Frame series, the D designates the specific interrupting capacity tier. For this model, it provides a 25 kA rating at 240VAC, 18 kA at 480Y/277VAC, and 14 kA at 600Y/347VAC.
