Product FAQs
5 answersHow do I decode the HLA36040SA catalog number?
In the PowerPacT nomenclature, "H" stands for the H-Frame, "L" indicates the interrupting rating of 100kAIC at 480VAC, "A" specifies an I-Line connection on the line side with lugs on the load side, "3" is for three poles, "6" denotes the 600V maximum AC rating, "040" represents the 40A current rating, and "SA" indicates a factory-installed 120VAC shunt trip.
How does the HLA36040SA connect within an I-Line panelboard?
It utilizes a plug-on I-Line connection on the line side to attach directly to the panelboard bus, while the load side features standard lugs that accept 14 AWG to 3/0 AWG aluminum or copper wire.
How does the factory-installed shunt trip on the HLA36040SA operate?
The included 120VAC shunt trip allows the breaker to be tripped remotely when a voltage signal is applied to the accessory terminals. This is frequently used for emergency power-off (EPO) circuits or safety interlocks.
Can the trip settings on the HLA36040SA be adjusted in the field?
No, this breaker features a thermal-magnetic trip unit with fixed Long-Time (L) and Instantaneous (I) settings. Neither the thermal overload nor the magnetic short-circuit protection can be adjusted.
Is the HLA36040SA suitable for reverse-feed applications?
Yes, this breaker is rated for reverse feeding. This allows the breaker to be backfed from the lug side when required by specific switchboard or generator configurations, provided the installation complies with local electrical codes.
