Product FAQs
10 answersWhat current rating should I use when selecting the Square D HGL36100SA?
Its rated current is 100A. Use that rating when evaluating load requirements and conductor protection, with conductor sizing based on the applicable installation requirements.
How should I select this breaker for an AC or DC circuit?
Its rated voltage is 600VAC or 250VDC. Select by both circuit voltage and AC or DC operation, then check the interrupting rating at the application voltage.
How much available fault current can this breaker interrupt?
Its interrupting ratings are 65kA at 240VAC, 35kA at 480VAC, 18kA at 600VAC, and 20kA at 250VDC. Choose the rating for your circuit voltage and ensure it is at least equal to the available fault current at the installation point.
Can I adjust the thermal or magnetic trip settings?
Both the thermal and magnetic trip settings are fixed. Thermal-magnetic operation provides long-time overload protection and instantaneous short-circuit protection, so select it where fixed trip characteristics meet the circuit's protection requirements.
What conductor sizes and materials can the lugs accept?
The lug conductor range is 14 AWG through 3/0 AWG for copper or aluminum. Select a conductor within that range while meeting the circuit's ampacity and installation requirements.
What mounting style and dimensions should I account for during layout?
This is a unit-mount breaker measuring 4.09 in wide, 6.40 in high, and 3.40 in deep. Use those dimensions when planning the mounting layout, with additional space for conductor routing and installation access.
What does the current-limiting feature mean for circuit protection?
Current-limiting operation reduces the peak fault current and energy let through during interruption. Consider this feature when evaluating fault-related stress on the circuit, alongside the interrupting rating and available fault current.
Why does the HACR rating matter when selecting a breaker?
HACR refers to heating, air-conditioning, and refrigeration applications. This rating is relevant when those equipment requirements call for a HACR-rated breaker; also check the required current, voltage, and interrupting ratings.
Which standards should I consider when reviewing project requirements?
The breaker carries UL 489, CSA C22.2 No. 5, IEC 60947-2, and NEMA AB 1 standards. Compare these with the standards required for the project, together with the breaker's electrical ratings.
Does the Square D HGL36100SA have a neutral connection?
The breaker has 3 poles and no neutral connection. Plan phase-conductor terminations at the breaker and neutral wiring separately.
