Product FAQs
6 answersWhat legacy Square D breakers does the HDA261101 replace?
The HDA261101 is the modern replacement for legacy 110A K-frame I-Line breakers, such as the KA26110AB and KH26110AB. It fits the same Square D I-Line panelboards and switchboards.
What does the "HDA" prefix mean in the HDA261101 catalog number?
In the Square D PowerPacT catalog numbering system, "H" stands for the H-frame breaker family, "D" indicates the interrupting rating (14kA at 600VAC, 18kA at 480VAC, 25kA at 240VAC), and "A" specifies an I-Line plug-on connection.
What phase connection does the HDA261101 use on an I-Line bus?
The HDA261101 is configured for an AB phase connection. If your installation requires an AC or BC phase connection, you will need catalog numbers HDA261102 or HDA261104, respectively.
What is the magnetic trip adjustment range for the HDA261101?
This 110A breaker features a fixed thermal and adjustable magnetic trip unit. The instantaneous magnetic trip can be adjusted between 900A and 1700A.
What does the "LI" trip function code indicate on this breaker?
The "LI" designation means the thermal-magnetic trip unit provides Long-Time (L) overload protection and Instantaneous (I) short-circuit protection.
Does the HDA261101 include a push-to-trip feature?
Yes, all PowerPacT H-frame circuit breakers feature an integral push-to-trip button on the cover. This allows you to manually trip the breaker to verify the mechanical operation of the trip mechanism.
