Built for heavy-duty power distribution, the Schneider Electric JJP36225 is a 3-pole, 225A molded case circuit breaker from the PowerPacT family. It installs into Square D NQ and NF panelboards, as well as industrial control panels. Equipped with fixed thermal and adjustable magnetic trip functions, this unit-mount breaker delivers reliable LI protection. The J-interrupting tier provides 65 kAIC at 480VAC, while the Visi-Trip feature allows for rapid fault identification.
Which panelboards and switchboards are compatible with the JJP36225?
This unit-mount breaker is designed for use in Square D NQ and NF panelboards, QED switchboards, Model 6 Motor Control Centers, and industrial control panels. It is not compatible with I-Line panelboards.
Does the JJP36225 come with mounting lugs installed?
Yes, this unit-mount breaker includes standard line and load lugs that accept 3/0 AWG to 350 kcmil aluminum or copper wire.
How does the JJP36225 differ from models like the JJA36225 or JGA36225?
The JJP36225 is a unit-mount breaker that connects via wire lugs on both ends. Models like the JJA36225 or JGA36225 are I-Line breakers designed to plug directly onto the buswork of a Square D I-Line panelboard.
Can I adjust the trip settings on the JJP36225?
The thermal trip element is fixed at 225A to provide standard overload protection. However, the magnetic trip element is adjustable, allowing you to fine-tune the instantaneous short-circuit response for your specific motor or equipment load.
What does the second "J" in the JJP36225 catalog number indicate?
The second letter in the Square D PowerPacT catalog number denotes the interrupting capacity. The "J" rating provides up to 100kA at 240VAC, 65kA at 480VAC, and 25kA at 600VAC.
Does the JJP36225 feature a push-to-trip button?
Yes, this breaker includes a built-in push-to-trip button on the faceplate. This safety feature allows electricians to manually trip the breaker to verify the mechanical operation of the trip mechanism before maintenance.
