Product FAQs
9 answersWhat does the LV suffix indicate on the HLL36015LV catalog number?
The LV suffix designates that this PowerPacT H-Frame breaker includes a factory-installed control wire tap on the OFF (load) end. This allows for convenient auxiliary power access or external signaling in control panels.
Can the HLL36015LV replace older Square D circuit breakers?
Yes, the PowerPacT H-Frame HLL36015LV provides a direct, modern upgrade path for legacy FCL36015 molded case circuit breakers.
Is the HLL36015LV suitable for reverse-fed applications?
Yes, this thermal-magnetic breaker is approved for reverse-fed applications, allowing line power to be connected to either the top or bottom terminals depending on panelboard layout.
How is the HLL36015LV installed in a panel?
This is a unit-mount circuit breaker. It fastens directly to the enclosure backpan or mounting plate using hardware and connects via standard line and load lugs, rather than plugging onto an I-Line bus.
Can the trip settings be adjusted on the HLL36015LV?
No, this breaker features a non-interchangeable thermal-magnetic trip unit with fixed long-time (thermal) and fixed instantaneous (magnetic) trip functions.
Does the HLL36015LV offer current-limiting protection?
Yes, this PowerPacT H-Frame breaker features current-limiting performance. It reduces the peak let-through current and energy during a short circuit, providing enhanced protection for downstream equipment.
How can I visually verify if the HLL36015LV has tripped?
The breaker features a visual trip indicator. When a fault occurs, the toggle handle automatically moves to a central tripped position between ON and OFF, providing clear confirmation for maintenance personnel.
Is the HLL36015LV rated for direct current (DC) systems?
Yes, in addition to AC networks, this breaker is rated for DC applications up to 500VDC, making it suitable for industrial automation and DC power supplies.
Is the HLL36015LV suitable for HVAC equipment?
Yes, this breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment.
