Product FAQs
7 answersWhat wire sizes are accepted by the lugs on the JJP36250?
The factory-installed lugs accept aluminum or copper conductors ranging from 3/0 AWG to 350 kcmil. Ensure you torque the lug screws to the manufacturer specifications printed on the breaker faceplate during installation.
Which panelboards and switchboards are compatible with this breaker?
The JJP36250 is designed for use in Square D NQ and NF panelboards, QED switchboards, Model 6 Motor Control Centers, and custom industrial control panels. It is a unit-mount breaker, meaning it fastens directly to the mounting pan or bracket rather than plugging into an I-Line bus.
What does the J interrupting rating indicate on the JJP36250?
In the Square D PowerPacT nomenclature, the second J indicates a high interrupting rating of 65 kAIC at 480VAC. This makes it suitable for commercial and industrial systems with higher available fault currents compared to standard D-rated or G-rated breakers.
How do I adjust the trip settings on the JJP36250?
This breaker features a thermal-magnetic trip unit with fixed thermal and adjustable magnetic settings. You can adjust the instantaneous magnetic trip threshold using the dial on the front of the breaker to coordinate with downstream loads.
What type of protection does the LI trip function provide?
The LI designation stands for Long-Time and Instantaneous protection. Long-Time protects the circuit against sustained overloads, while the Instantaneous function provides immediate tripping during severe short circuits to prevent equipment damage and fire hazards.
Can I use the JJP36250 to replace an older Square D J-frame breaker?
Yes, this PowerPacT J-frame breaker can often replace legacy Square D J-frame models with similar specifications. Because it is a unit-mount configuration, verify that your existing mounting hardware and enclosure space match the current PowerPacT dimensions.
Can the JJP36250 be used in DC applications?
Yes, this breaker is rated for use in DC circuits up to 250VDC, where it provides an interrupting rating of 20 kAIC. This makes it suitable for specific industrial control and battery system applications.
