Product FAQs
6 answersWhat enclosures are compatible with the Siemens SJD69300 circuit breaker?
The SJD69300 fits Siemens JD-frame enclosures, including the J6N1 (NEMA 1 indoor), J6N3R (NEMA 3R outdoor), and J6N12 (NEMA 12 dust-tight).
What is the difference between the Siemens JD63B300 and the SJD69300?
Both breakers share the same 300A, 3-pole JD frame footprint. However, the JD63B300 uses a standard thermal-magnetic trip unit, while the SJD69300 features a Sensitrip III solid-state electronic trip unit for more precise, adjustable protection.
What is the difference between the SJD69300 and the SJD69300NT?
The standard SJD69300 features Long-Time and Instantaneous (LI) trip functions. The SJD69300NT includes a Short-Time trip function, providing Long-Time, Short-Time, and Instantaneous (LSI) protection for enhanced coordination.
What does the "G" stand for in the SJD69300G catalog number?
The "G" suffix indicates that the breaker includes integral ground fault protection (LIG trip functions) in addition to the standard long-time and instantaneous protection found on the base SJD69300.
Can the Siemens SJD69300 be reverse fed?
Yes. Because the SJD69300 is built with a non-interchangeable electronic trip unit, it meets UL 489 requirements for reverse feeding applications.
Which lug kits are standard for the SJD69300 breaker?
The standard line and load lug kit for this JD-frame breaker is the TA2J6500. This aluminum body lug accepts two wires per phase ranging from 3/0 AWG to 500 kcmil.
