Product FAQs

6 answers
Which panelboards are compatible with the BDA160401 circuit breaker?

This breaker is designed exclusively for Square D I-Line panelboards and switchboards. It utilizes the I-Line plug-on mounting system to connect directly to the bus stack.

What are the acceptable wire sizes for the terminals on this breaker?

The factory-installed lugs accept wire gauges from 14 AWG up to 2/0 AWG. The terminals are rated for both aluminum and copper conductors.

Is the BDA160401 suitable for direct current (DC) applications?

Yes, this breaker is rated for use in DC systems up to 125VDC, where it provides an interrupting capacity of 10kA.

What does the D signify in the BDA160401 catalog number?

In the Square D PowerPacT B-Frame nomenclature, the D indicates the interrupting rating tier. For this model, it signifies an 18kA interrupting capacity at 480Y/277VAC and 14kA at 600Y/347VAC.

Can I adjust the trip settings on the BDA160401?

No, this specific PowerPacT B-Frame breaker features fixed thermal and fixed magnetic trip elements. The long-time and instantaneous trip functions cannot be field-adjusted.

How does the I-Line mounting style benefit panel builders?

The I-Line plug-in design allows the breaker to snap directly onto the panelboard bus stack without the need for additional mounting hardware or wire connections to the bus. This significantly reduces installation time and ensures a secure connection.
