Product FAQs
6 answersWhat enclosures and panels are compatible with the JDC3150?
This breaker is designed for use in Eaton Series C panelboards, switchboards, motor control centers, and legacy Westinghouse panelboards that accept J-frame breakers.
Can the JDC3150 replace older Westinghouse JD or HJD breakers?
Yes, the JDC3150 is part of the Series C J-frame family and shares the same physical dimensions as JD3150 and HJD3150 breakers. It can be used as a direct replacement, offering a higher interrupting capacity.
What does the C in the JDC3150 frame designation indicate?
The C indicates it is the ultra-high interrupting capacity version of the J-frame, rated to safely interrupt up to 100kA at 480VAC and 200kA at 240VAC.
Is the JDC3150 suitable for reverse-feed applications?
Yes, this breaker is suitable for reverse-fed applications, making it versatile for use as a main breaker or in back-fed scenarios within a panel.
Can the trip unit on the JDC3150 be replaced or upgraded?
Yes, the JDC3150 features an interchangeable trip unit design. This allows panel builders to swap the thermal-magnetic trip unit if different protection parameters are required in the future without replacing the entire breaker frame.
How do I adjust the magnetic trip settings on the JDC3150?
The JDC3150 includes an adjustable magnetic trip function. Electricians can use the adjustment dials on the face of the trip unit to fine-tune the instantaneous short-circuit pickup levels based on the specific load requirements.
