Engineered for heavy-duty commercial and industrial applications, the Eaton JDB3200 delivers 200A, 3-pole molded case circuit protection from the proven Series C family. It provides reliable overcurrent defense for demanding electrical systems. This J-Frame unit mounts into compatible Eaton switchboards, motor control centers, and panelboards. It serves as a drop-in replacement for legacy JD3200 breakers, ensuring seamless facility upgrades.
Can I use the Eaton JDB3200 to replace an older Westinghouse JDB3200?
Yes. Eaton acquired the Westinghouse distribution equipment line. The Eaton JDB3200 is a direct replacement for the legacy Westinghouse JDB3200, sharing the exact physical dimensions, mounting footprint, and electrical ratings.
What does the B in the JDB3200 catalog number indicate?
The B indicates that the circuit breaker is suitable for reverse feed applications. It does not have specific line and load markings, and the thermal magnetic trip unit is factory sealed to the breaker frame, making it non-interchangeable.
What is the difference between the JDB3200 and the JD3200 or HJD3200?
All three are 200A, 3-pole J-Frame breakers. The JDB3200 features a factory sealed, non-interchangeable trip unit and is suitable for reverse feeding. The JD3200 and HJD3200 have interchangeable trip units, with the HJD offering a higher interrupting capacity of 65kAIC at 480VAC compared to 35kAIC for the JDB and JD.
Can the JDB3200 be reverse fed?
Yes. Because it is a JDB type with no dedicated line and load markings, it is fully rated for reverse feed installations in compatible panelboards, switchboards, and enclosures.
What types of equipment accept the JDB3200?
This unit mount breaker is designed for installation in Eaton, Cutler-Hammer, and legacy Westinghouse Series C panelboards, switchboards, motor control centers, and standalone enclosures.
What does the LI trip function code mean on this breaker?
The LI designation indicates that the thermal magnetic trip unit provides Long-Time (L) protection for overloads and Instantaneous (I) protection for short circuits. Both the thermal and magnetic trip points are fixed on the JDB3200.
Is the JDB3200 suitable for DC electrical systems?
Yes, this breaker is rated for use in DC applications up to 250VDC, providing a DC interrupting capacity of 10kAIC.
Is the Eaton JDB3200 HACR rated?
Yes, this Series C molded case circuit breaker is HACR rated, making it suitable for group motor applications in heating, air conditioning, and refrigeration equipment.
