Product FAQs
6 answersDoes the BDA36090 replace older FA frame breakers?
Yes, the PowerPacT B-frame I-Line circuit breakers are the direct modern replacements for legacy Square D FA and FH frame breakers, including the FA36090. They fit into the same I-Line panelboard mounting space.
What do the letters in the BDA36090 catalog number signify?
"B" designates the PowerPacT B-frame family. "D" indicates the interrupting rating tier, which is 18kA at 480VAC. "A" specifies the I-Line plug-on mounting style.
What is the torque specification for the load lugs on this breaker?
For 14 AWG to 10 AWG wire, tighten the lugs to 31.9 to 38.9 lb-in. For 8 AWG to 2/0 AWG wire, tighten to 44.3 to 54.9 lb-in.
How does the BDA36090 connect to the panelboard?
This breaker utilizes an I-Line style plug-on connection for the line side, which snaps directly onto the panelboard bus. The load side features mechanical lugs that accept 14 AWG to 2/0 AWG aluminum or copper wire.
Does this breaker have a manual trip feature for testing?
Yes, all PowerPacT B-frame circuit breakers include an integral push-to-trip button on the cover, allowing you to manually trip the breaker to verify the operating mechanism.
What is the benefit of the dual-break rotating contacts in this breaker?
The PowerPacT B-frame utilizes dual-break rotating contacts that rapidly repel during a short circuit. This extinguishes the fault current before it fully develops, reducing peak let-through energy and enhancing overall equipment protection.
