Product FAQs
8 answersHow should I apply the 100A rating of the Square D HDA36100U43X to continuous loads?
The breaker has a 100A rated current and an 80% continuous load rating. Use the continuous load rating when sizing circuits that carry sustained loads.
What protection does the adjustable electronic LSI trip offer?
The MicroLogic 5.2 A electronic trip unit offers adjustable LSI protection: long-time overload, short-time short-circuit and instantaneous short-circuit protection. These functions let you tailor trip settings to the circuit's protection and coordination requirements.
What conductor materials and sizes can I terminate on the load side?
The load-side lug accepts copper or aluminum conductors from 14 AWG through 3/0 AWG. Choose a conductor within that range that also meets the circuit's ampacity and installation requirements.
How do the three poles and ABC phase connection affect installation?
This is a three-pole breaker for three-phase circuits with an ABC phase connection. Use the ABC connection arrangement to guide phase assignment during installation.
What dimensions should I use when planning the physical layout?
Use a width of 4.09 in, height of 6.4 in and depth of 3.4 in when planning the breaker's physical layout. These dimensions define the breaker body space to account for in the installation design.
What operating temperature range should I consider for the installation?
The operating temperature range is -25 to 70 °C. Choose an installation environment that keeps the breaker within this range during operation.
What does the HACR rating mean when selecting this breaker?
HACR refers to heating, air-conditioning and refrigeration applications. The HACR rating supports selection for those applications, with current, voltage and interrupting ratings chosen to meet the equipment's electrical requirements.
How do I check the frequency rating when selecting this breaker for an AC circuit?
The 50/60Hz rating permits use at either rated AC frequency. Match the system frequency to this rating, and check voltage and interrupting ratings when selecting the breaker.
