Product FAQs
9 answersHow should I select the Square D HGA36100U43X for current and voltage?
This molded case circuit breaker is rated 100A and 600VAC. Use the current rating in your load and conductor protection calculations, and select it for an AC circuit whose voltage does not exceed 600VAC.
How much available fault current can this breaker interrupt?
The interrupting ratings are 65kA at 240VAC, 35kA at 480VAC, and 18kA at 600VAC. Compare the available fault current at the installation point with the rating for the circuit voltage; it must not exceed that rating.
What does the adjustable electronic LSI trip do?
LSI includes long-time, short-time, and instantaneous trip functions. These address sustained overloads and fault conditions with different response times. Adjustable electronic tripping supports setting the protection for the load and coordinating it with other circuit protection.
What conductors can I terminate at the lugs?
The lug terminals accept copper or aluminum conductors from 14 AWG through 3/0 AWG. Choose a conductor within that range that also satisfies the circuit's ampacity and installation requirements; terminal acceptance alone does not determine conductor sizing.
What does the HACR rating mean for HVAC applications?
The HACR rating covers heating, air-conditioning, and refrigeration applications. It is relevant when selecting branch-circuit protection for HVAC equipment, alongside the equipment's current, voltage, and overcurrent protection requirements.
What dimensions should I use when planning installation space?
The breaker measures 4.09 in wide, 6.40 in high, and 3.40 in deep. Use these dimensions to plan the space occupied by the breaker, while accounting separately for conductor routing and working clearances.
What temperature range should I consider when selecting this breaker?
The temperature rating is -25C to 70C. Compare the expected installation temperatures with this range when selecting the breaker for the application.
Which circuit breaker standards does this model meet?
The standards include UL 489, CSA C22.2 No. 5, IEC 60947-2, and NEMA AB 1. Use these standards when checking the circuit breaker requirements for your project and jurisdiction.
What does the 3-pole configuration mean for circuit connections?
The Square D HGA36100U43X has 3 poles and a 3-phase configuration. Account for three phase-conductor paths when planning the circuit connections.
