Product FAQs
10 answersCan the Square D PGA36060CU33A be selected for a 600A continuous load?
Its 600A rated current and 100% continuous load rating allow selection at the full rated current for continuous-load applications.
How do I select this breaker for circuit voltage and available fault current?
The breaker is rated 600VAC, with interrupting ratings of 65kA at 240VAC, 35kA at 480VAC and 18kA at 600VAC. At the circuit voltage, the interrupting rating must meet or exceed the available fault current at the installation point.
What protection functions does the MicroLogic 5.0 trip unit offer?
The MicroLogic 5.0 electronic trip unit provides LSI protection: long-time protection for overloads, short-time protection for short circuits with a delay, and instantaneous protection for high fault currents. These functions support protection coordination when selecting and setting the breaker.
How far can I adjust the long-time pickup?
The adjustable trip range is 240-600A, with long-time pickup adjustable from 0.4-1 x Ir. Set the pickup to suit the circuit's load and conductor protection requirements rather than assuming the 600A current rating is the required setting.
What conductor sizes and materials can I use at the load-side lugs?
The load-side lug conductor range is (3) 3/0 AWG to 500 kcmil, Cu/Al. Select copper or aluminum conductors within that range, with ampacity appropriate for the circuit.
What torque should I use for the load-side terminal connections?
The terminal torque is 442.5 lb-in for the load-side lug connections. Use a calibrated torque tool to achieve the required clamping force.
What dimensions should I use when planning the installation layout?
The breaker measures 12.86 in high, 8.27 in wide and 8.05 in deep. Use these body dimensions when planning equipment layout and installation space.
What phase and frequency ratings should I check before selecting this breaker?
This is a 3-pole breaker for 3-phase service with an ABC phase connection and a 50/60Hz frequency rating. Use the phase arrangement and operating frequency as electrical selection criteria.
When is the HACR rating relevant to breaker selection?
HACR refers to heating, air-conditioning and refrigeration applications. This rating is relevant when selecting protection for equipment that calls for an HACR-rated circuit breaker.
What operating temperature range should I use for installation planning?
The operating temperature range is -25 to 70 °C. Plan the installation so the breaker's operating temperature remains within that range.
