Product FAQs
8 answersCan the HDA260501 replace older Square D FA series breakers?
Yes, the PowerPacT H-frame HDA260501 is a direct replacement for the discontinued FA26050 I-Line circuit breaker. It mounts into the same Square D I-Line panelboards and switchboards.
What does the 1 at the end of the HDA260501 catalog number signify?
The 1 indicates that this 2-pole breaker is factory-configured for an AB phase connection on the I-Line bus.
How does the HDA260501 mount into a panel?
It features an I-Line style plug-in connection. The line side plugs directly onto the panelboard bus, while the breaker is secured to the backpan with a built-in mounting bracket. The load side uses standard mechanical lugs for field wiring.
Can I use the HDA260501 in a standard QO or Homeline load center?

The factory-installed load lugs accept 14 AWG to 3/0 AWG aluminum or copper conductors.

What type of trip unit is installed in the HDA260501?
It is equipped with a non-interchangeable thermal-magnetic trip unit that provides fixed long-time (thermal) overload protection and fixed instantaneous (magnetic) short circuit protection.
