Product FAQs
7 answersWhat does the U33X in the JDL36250U33X catalog number signify?
The U33X designates a Micrologic 3.2 S electronic trip unit. This provides standard LSI (Long-time, Short-time, and Instantaneous) trip functions, allowing for precise coordination and adjustable fault clearing in your electrical system.
Can the JDL36250U33X be used in DC voltage applications?
No. While some J-Frame breakers support DC voltage, models equipped with Micrologic electronic trip units like the JDL36250U33X are rated for AC voltage only. DC applications require a breaker with a thermal-magnetic trip unit.
Is this breaker suitable for Square D I-Line panelboards?
No, the JDL36250U33X is a unit-mount breaker designed for feed-thru installations on a backpan. For an I-Line panelboard, you need the I-Line version, which typically uses the prefix JDA instead of JDL.
How does the JDL36250U33X differ from the JGL36250U33X or JLL36250U33X?
The difference is the interrupting rating. The JDL features a D-rated breaking capacity of 18kA at 480VAC. The JGL (G-rated at 35kA) and JLL (L-rated at 100kA) offer higher short-circuit interrupting capacities for systems with higher available fault currents.
Does the Micrologic 3.2 S trip unit include ground fault protection?
No, the U33X trip unit provides LSI protection only. If your application requires equipment ground fault protection (LSIG), you will need a breaker equipped with a U44X or U54X Micrologic trip unit.
Is the JDL36250U33X rated for 100 percent continuous current?
Standard PowerPacT J-Frame breakers like this one are 80 percent rated. If your application requires a 100 percent continuous current rating, you must source a catalog number with a C suffix, such as JDL36250CU33X, and install it in a properly rated enclosure.
Can I use aluminum wiring with the JDL36250U33X?
Yes, the standard factory lugs on this PowerPacT J-Frame breaker are dual-rated for both aluminum and copper (Al/Cu) conductors. They accept wire sizes ranging from 3/0 AWG to 350 kcmil.
