Product FAQs
9 answersCan I adjust the current setting on the Square D HLL36100U31X?
This 100A breaker has an adjustable trip range of 50-100A. Use that range to select a setting appropriate for the load and conductor protection requirements.
What protection does the MicroLogic 3.2 electronic trip provide?
The MicroLogic 3.2 electronic trip provides long-time and instantaneous protection, coded LI. Long-time protection responds to sustained overloads, while instantaneous protection responds to high-current faults without an intentional delay.
How do I select this breaker for the available fault current?
Its interrupting ratings are 125kA at 240VAC, 100kA at 480VAC, and 50kA at 600VAC. Compare the available fault current at the installation point with the rating applicable to the circuit voltage.
What conductor sizes and materials can the lug terminals accept?
The lug terminals accept copper or aluminum conductors from 14 AWG through 3/0 AWG. Select a conductor within that terminal range with ampacity appropriate for the circuit and protection setting.
What mounting style and dimensions should I plan around?
This H-frame breaker uses unit mounting and measures 4.09 in wide, 6.40 in high, and 3.40 in deep. Use these dimensions when planning the mounting layout and physical space.
What temperature range should I consider for installation?
The temperature rating is -25C to 70C. Consider the temperature at the breaker location when selecting the installation environment.
What does the current-limiting feature mean for fault protection?
Current limiting reduces the peak current and energy let through during a short circuit in its current-limiting operating range. Consider this feature when evaluating fault protection, together with the interrupting rating at the circuit voltage.
What does the HACR rating mean when selecting this breaker?
HACR means heating, air conditioning, and refrigeration. This rating is relevant when selecting overcurrent protection for that equipment; match the breaker selection to the equipment's electrical requirements.
How does the 600VAC rating guide breaker selection?
The Square D HLL36100U31X has a maximum rated voltage of 600VAC. Use this as the AC voltage ceiling when selecting the breaker for the circuit's operating voltage.
