Product FAQs
5 answersWhat panelboards accept the HDA36050SA circuit breaker?
This breaker features an I-Line style plug-in connection, making it compatible with Square D I-Line panelboards and switchboards.
What does the SA suffix in the HDA36050SA catalog number indicate?
The SA suffix denotes a factory-installed 120VAC shunt trip release coil. This allows the breaker to be tripped remotely for emergency shutdowns or automated control schemes.
Which legacy Square D breaker does the HDA36050SA replace?
This PowerPacT H-frame breaker supersedes older 50A F-frame I-Line breakers equipped with a 120VAC shunt trip, such as the FA36050-1021.
Does the HDA36050SA require a specific lug kit for copper wire?
No, the standard factory lugs are dual-rated for both aluminum and copper conductors ranging from 14 AWG to 3/0 AWG.
How does the thermal-magnetic trip unit on the HDA36050SA operate?
The trip unit provides fixed long-time protection against overloads using a bimetallic element, and fixed instantaneous protection against short circuits via a magnetic assembly.
