Description
Square D HLP36030 molded case circuit breaker is rated 30A, 600VAC, 250VDC and 500VDC, with 3 poles and 3 phases. This PowerPacT H-frame breaker has unit mounting, a thermal magnetic trip with fixed thermal and fixed magnetic settings, LI trip function and standard protection. UL 489 interrupting ratings are 125kA at 240VAC, 100kA at 480VAC, 50kA at 600VAC, 20kA at 250VDC and 50kA at 500VDC. IEC Ics interrupting ratings are 125kA at 220/240VAC, 100kA at 380/440/415VAC, 50kA at 500/525VAC, 20kA at 250VDC and 20kA at 500VDC. Terminal connections are a line-side terminal nut and load-side lug, with a conductor range of 14-3/0 AWG Cu/Al. Dimensions are 4.09 in wide, 6.4 in high and 3.4 in deep. Approvals are CE, UL, CSA, NEMA, NOM and IEC.Specifications

Product FAQs
10 answersHow should I size a continuous load for the Square D HLP36030?
The breaker is rated 30A with an 80% continuous load rating. Size the continuous load to remain within 80% of the rated current rather than using the full 30A continuously.
How do I select this breaker for the available fault current on an AC circuit?
The UL 489 interrupting ratings are 125kA at 240VAC, 100kA at 480VAC and 50kA at 600VAC. Select using the rating at the circuit voltage, ensuring it meets or exceeds the available fault current at the installation point.
Which interrupting ratings apply when selecting this breaker for a DC circuit?
At 250VDC, both UL 489 and IEC Ics ratings are 20kA. At 500VDC, the UL 489 rating is 50kA and the IEC Ics rating is 20kA. Use the rating under the applicable standard when comparing against available fault current.
Can I adjust the overload and short-circuit trip settings?
The thermal and magnetic trip settings are fixed. Thermal-magnetic protection responds to sustained overloads through the thermal element and short circuits through the magnetic element, so selection must account for fixed rather than field-adjustable settings.
What copper or aluminum conductor sizes can I terminate?
The conductor range is 14-3/0 AWG for copper or aluminum. Use this range to check terminal acceptance, and select conductor size according to the circuit load and installation requirements.
What connection types should I plan for on the line and load sides?
The line side uses a terminal nut, while the load side uses a lug. Plan the terminations around these different connection types rather than treating both sides as lug connections.
What mounting method and physical dimensions should I plan around?
This is a unit-mount molded case circuit breaker measuring 4.09 in wide, 6.4 in high and 3.4 in deep. Use these dimensions when laying out the mounting location and planning space for conductor routing.
What operating temperature range should I consider for the installation location?
The operating temperature range is -25 to 70 °C. Consider the temperature at the breaker location when selecting it for the installation environment.
How should I use the HACR rating when selecting a breaker?
HACR means heating, air-conditioning and refrigeration. Use the HACR rating as a selection criterion when the equipment requires that rating, alongside current, voltage and interrupting ratings.
What should I check about phase count and frequency when selecting this breaker?
The breaker has three poles, a three-phase configuration and a 50/60Hz rating. Check phase count and operating frequency as separate selection criteria, along with voltage and interrupting ratings.
