Product FAQs
8 answers
How should I use the 100A rating when selecting the Square D FHL361008041?
The 100A rating is the breaker's rated current. Coordinate this rating with the circuit load, conductor ampacity, and applicable circuit-sizing requirements.
What circuit voltages can I select this breaker for?
The voltage ratings are 240VAC, 480VAC, 600VAC, and 250VDC. Match the circuit's voltage and AC or DC supply type to the appropriate rating when selecting the breaker.
How do I evaluate its interrupting rating for a 480VAC installation?
Compare the available fault current at the installation point with the 25kAIC interrupting rating at 480VAC. The available fault current must not exceed the breaker's interrupting rating.
Can I adjust the thermal or magnetic trip settings?
The thermal and magnetic trip settings are fixed. Thermal-magnetic protection uses a long-time response for sustained overloads and an instantaneous response for high fault currents, so select it for applications that do not require adjustable trip settings.
What conductor sizes can the lug terminals accept?
The lug terminals accept conductors from 14 AWG through 1/0 AWG. Select a conductor within that terminal range while also meeting the circuit's ampacity requirements; terminal acceptance alone does not determine conductor sizing.
What mounting style and dimensions should I account for?
This unit-mount breaker measures 6 in high, 4.5 in wide, and 3.13 in deep. Use the mounting style and body dimensions when planning the installation layout.
Is this a three-pole breaker for a three-phase circuit?
Yes. It has 3 poles for a 3-phase application, providing a breaker pole for each phase conductor. Use the pole count and phase configuration when planning the circuit arrangement.
What does the HACR marking mean for application selection?
HACR refers to heating, air conditioning, and refrigeration. Use this marking when selecting protection for equipment applications that call for a HACR-rated circuit breaker.
