Product FAQs
6 answersWhat does the C in the PKL36060CU33A catalog number indicate?
The C designates that this breaker is 100 percent rated. This allows it to carry its full 600A continuous current rating without the standard 80 percent derating requirement, provided it is installed in a properly sized and ventilated enclosure.
What type of trip unit is installed in this breaker?
It includes a MicroLogic 5.0 electronic trip unit, indicated by the U33A suffix in the catalog number. This provides adjustable Long-time, Short-time, and Instantaneous (LSI) protection for precise system coordination.
Can the trip unit on the PKL36060CU33A be swapped in the field?
Yes, PowerPacT P-frame breakers feature interchangeable MicroLogic trip units. This allows you to upgrade or change the protection functions in the field without replacing the entire breaker frame.
Is this breaker suitable for I-Line panelboards?
No, the PKL36060CU33A is a unit-mount, feed-thru breaker with lugs on both the line and load sides. For I-Line panelboards, you must use the I-Line version of the P-frame breaker, which features a plug-on jaw connection on the line side.
Can this breaker be used in a drawout configuration?
No, the PKL36060CU33A is configured as a fixed unit-mount breaker. Drawout applications require a different mounting base and breaker configuration within the PowerPacT P-frame family.
Does this breaker include a push-to-trip feature?
Yes, it features an integral push-to-trip button on the front cover. This allows you to manually trip the breaker to verify the mechanical operation of the tripping mechanism prior to maintenance.
