Product FAQs

6 answers
What does the "1" at the end of the HDA261001 catalog number indicate?

The "1" indicates that this 2-pole breaker is configured for an A-B phase connection on the I-Line bus.

Can the HDA261001 replace older Square D F-frame breakers?

Yes, this PowerPacT H-frame breaker is the direct replacement for the obsolete FA26100AB I-Line circuit breaker.

What is the lug torque specification for the load-side terminals on this 100A breaker?

For the mechanical load lugs, the tightening torque is 44 lb-in (5 N.m) for 14 to 10 AWG wire, and 124 lb-in (14 N.m) for 8 to 3/0 AWG wire.

Does this breaker require a separate mounting hardware kit for installation?

No. As an I-Line style plug-in breaker, it features built-in mounting jaws on the line side that attach directly to the panelboard bus, requiring no additional hardware kits.

How can I manually test the mechanical operation of this breaker?

All PowerPacT H-frame circuit breakers feature an integral push-to-trip button on the front cover. Pressing this button manually trips the breaker to verify the mechanical linkage is operating correctly.

Is this breaker 80% or 100% rated for continuous current?

The HDA261001 is a standard 80% rated circuit breaker.
