Product FAQs
8 answersWhat is the magnetic trip adjustment range for the JDM36150?
The JDM36150 features an adjustable magnetic trip unit with a low hold current setting of 750A and a high trip current setting of 1500A.
What type of enclosures or panelboards accept the JDM36150?
As a unit-mount, bolt-on breaker, the JDM36150 is designed for installation in standard industrial control panels, switchboards, motor control centers, and unit-mount enclosures. It is not compatible with I-Line panelboards.
Can I use the JDM36150 in an I-Line panelboard?
No, the JDM36150 is a unit-mount breaker with bolt-on lug connections. For I-Line panelboards, you must use an I-Line version such as the JDA, JGA, JJA, or JLA series breakers.
How is the JDM36150 applied in DC circuits?
The JDM36150 is rated for up to 250VDC with a 20kAIC interrupting capacity. When installing in DC applications, you must follow Schneider Electric wiring diagrams for series pole connections to ensure proper arc extinguishing.
Can I replace the standard lugs on the JDM36150?
Yes, the PowerPacT J-Frame series supports field-interchangeable terminal options, allowing you to swap the standard mechanical lugs for alternate lug kits or terminal nuts depending on your application needs.
Is the JDM36150 suitable for reverse feeding?
Yes, standard thermal-magnetic PowerPacT J-Frame breakers like the JDM36150 are suitable for reverse feeding, as they do not contain electronic trip units with directional constraints.
What does the D in the JDM36150 catalog number signify?
The D indicates the standard interrupting rating tier within the PowerPacT J-Frame family, which provides 18kAIC at 480VAC and 14kAIC at 600VAC. Higher tiers like G, J, or L offer increased short-circuit protection.
Does the JDM36150 have a manual testing feature?
Yes, it includes an integral push-to-trip button on the cover, allowing you to manually trip the breaker to verify the mechanical operation of the trip mechanism.
