Product FAQs
5 answersIs the Square D PGL36080CU33A rated for 100 percent continuous current?
Yes, the C in the catalog number indicates this breaker is 100 percent rated. This allows it to carry its full 800A continuous current rating without the standard 80 percent derating, provided it is installed in an appropriately sized and ventilated enclosure.
What protection functions are provided by the U33A trip unit?
The U33A suffix designates a Micrologic 5.0 electronic trip unit. This provides adjustable Long-time, Short-time, and Instantaneous (LSI) protection, allowing panel builders to precisely coordinate the breaker with other devices in the electrical system.
Does the PGL36080CU33A support Zone Selective Interlocking?
Yes, the included Micrologic 5.0 trip unit features short-time Zone Selective Interlocking (ZSI). This allows the breaker to communicate with downstream devices to clear faults faster, reducing thermal and mechanical stress on the switchboard.
How does the PGL36080CU33A mount inside an enclosure?
The L in the PGL prefix indicates that this is a unit-mount breaker with factory-installed lugs on both the line and load sides. It is designed for feed-thru applications and bolts directly to the backpan of Square D P-Frame enclosures, QED switchboards, or Model 6 Motor Control Centers, unlike I-Line plug-on variants.
Does this breaker use True RMS sensing?
Yes, the Micrologic 5.0 electronic trip unit utilizes True RMS sensing to accurately measure current. This ensures reliable protection even in environments with high harmonic distortion from non-linear loads like variable frequency drives.
