Product FAQs
7 answersWhat panelboards are compatible with the HDA36020SA circuit breaker?
The HDA36020SA features an I-Line style plug-in connection, making it compatible with Square D I-Line panelboards and switchboards. It is not designed for standard load centers or unit-mount applications.
What does the "SA" suffix mean in the HDA36020SA catalog number?
The "SA" suffix indicates that this breaker includes a factory-installed 120VAC shunt trip. This allows the breaker to be tripped remotely for emergency shutdowns or automated control applications.
What is the interrupting capacity of the HDA36020SA at 600VAC?
While the specification table lists the 240VAC and 480VAC ratings, this D-interrupting class breaker also provides a 14kAIC rating when used on 600VAC systems.
Is the HDA36020SA rated for continuous operation at 100 percent of its current rating?
No, standard PowerPacT H-frame breakers like the HDA36020SA are 80 percent rated. Continuous loads should not exceed 16 Amps (80 percent of its 20A rating) for more than three hours.
How is the HDA36020SA wired and mounted?
The line side utilizes an integrated I-Line bracket to plug directly into the bus assembly of a Square D I-Line panelboard, eliminating the need for line-side wiring. The load side features mechanical lugs that accept aluminum or copper wire ranging from 14 AWG to 3/0 AWG.
Can the HDA36020SA replace older F-frame circuit breakers?
Yes, the PowerPacT H-frame series supersedes legacy Square D F-frame breakers. The HDA36020SA is a direct replacement for older 20A, 3-pole I-Line F-frame breakers equipped with a 120VAC shunt trip, such as the FA36020-1021.
How can I test the mechanical operation of the HDA36020SA?
PowerPacT H-frame breakers feature an integral push-to-trip button on the front cover. Pressing this button manually trips the breaker, allowing you to verify the mechanical operation of the tripping mechanism as part of regular maintenance.
