Product FAQs
7 answersWhat does the C in the JGL36250CU33X catalog number indicate?
The C designates that this circuit breaker is 100 percent rated for continuous current. It can carry its full 250A rating continuously when installed in a properly sized enclosure using 90 degree Celsius rated wire.
What trip unit is included with the JGL36250CU33X?
This breaker features a factory-installed Micrologic 3.2S electronic trip unit, designated by the U33X suffix. It provides adjustable Long-time, Short-time, and Instantaneous (LSI) protection settings for precise system coordination.
Can I reverse feed the JGL36250CU33X?
Yes, PowerPact J-frame breakers with Micrologic electronic trip units are suitable for reverse connection. You can land the incoming supply power on either the top or bottom lugs without affecting the trip unit functionality.
What enclosures or panels accept this JGL36250CU33X breaker?
This unit mount breaker is designed for use in Square D NF panelboards, switchboards, motor control centers, and individual industrial enclosures. Because it is a 100 percent rated breaker, it requires a unit mount configuration and is not available for I-Line bus connections.
What wire sizes are accepted by the standard lugs on this 250A breaker?
The factory-installed AL250JD lugs accept one aluminum or copper conductor per phase, ranging from 3/0 AWG to 350 kcmil.
How does the JGL36250CU33X differ from the JGL36250U33X?
The JGL36250CU33X is 100 percent rated for continuous current, whereas the standard JGL36250U33X is rated for 80 percent continuous current. Both share the same physical dimensions, 250A rating, and Micrologic 3.2S trip unit.
Can the JGL36250CU33X be used in DC applications?
No. The JGL36250CU33X is strictly rated for AC systems up to 600VAC. PowerPact J-frame breakers equipped with Micrologic electronic trip units are not rated for use in DC applications.
