Product FAQs
9 answersCan the Square D PGL36060CU31A serve a 600A continuous load?
This breaker has a 600A rated current and a 100% continuous-load rating. That permits selection for a 600A continuous load when installed for 100%-rated operation.
How do I select this breaker for system voltage and available fault current?
The rated voltage is 600VAC. Its UL 489 interrupting ratings are 65kA at 240VAC, 35kA at 480VAC and 18kA at 600VAC. Compare available fault current at the installation point with the interrupting rating for the system voltage.
What phase and frequency should I select this breaker for?
This is a 3-pole breaker for 3-phase circuits, rated for 50/60Hz. Use the pole count, phase and frequency ratings when selecting it for the circuit.
What protection does the MicroLogic 3.0 LI trip unit offer?
The MicroLogic 3.0 electronic trip unit has LI functions: long-time and instantaneous protection. Long-time protection addresses sustained overloads, while instantaneous protection responds to high-current faults without an intentional delay.
Can I adjust the long-time pickup?
Yes. The adjustable electronic trip provides a long-time pickup range of 0.4-1 x Ir. This adjustment sets the overload pickup threshold for the circuit's load and protection requirements.
What conductor sizes and materials can I use at the lugs?
The conductor range is (3) 3/0 AWG to 500 kcmil, using copper or aluminum conductors. Line- and load-side lug connections let you terminate both incoming and outgoing conductors; select conductors within that range.
What does the HACR rating mean for an HVAC application?
HACR means heating, air conditioning and refrigeration. The HACR rating is relevant when selecting a breaker for equipment that calls for HACR-rated circuit protection.
How much physical space should I allow for the breaker body?
The breaker measures 12.86 in high, 8.27 in wide and 8.05 in deep. Use these dimensions when planning the physical layout and space occupied by the breaker.
What operating-temperature range should I use when planning the installation?
The operating-temperature range is -25 to 70 °C. Use this range when evaluating the temperature at the breaker's installation location.
