Description
Designed for complex electrical systems, the Siemens SHJD69300NGT is a 3-pole, 300A Sentron MCCB. It features a Sensitrip solid-state trip unit with comprehensive LSIG protection, allowing adjustments for long-time, short-time, instantaneous, and ground-fault settings. This JD-frame breaker mounts into Siemens Sentron panelboards and SB switchboards. It is an exact substitute for the discontinued SHJD6B300LSIG. Rated 65 kAIC at 480VAC, it provides true RMS sensing for superior accuracy.Specifications

Product FAQs
6 answersWhat does the NGT suffix in the SHJD69300NGT catalog number indicate?
The NGT suffix indicates that the Sensitrip solid state electronic trip unit includes Long Time, Short Time, Instantaneous, and Ground Fault (LSIG) protection functions. The G specifically denotes ground fault protection configured for 3-phase, 3-wire systems.
Can I use the SHJD69300NGT on a 3-phase, 4-wire system?
Yes, but because the G suffix denotes a breaker configured for 3-phase, 3-wire systems, you must order the correct 4th wire neutral sensor transformer separately to provide accurate ground fault protection on a 4-wire system.
Is the SHJD69300NGT suitable for reverse feed applications?
No. According to Siemens specifications, SHJD6 high interrupting breakers are not acceptable for reverse connection applications. Only standard SJD6 and current limiting SCJD6 frames are rated for reverse feed.
What equipment is compatible with the SHJD69300NGT breaker?
This JD frame breaker is designed for unit mounting in Siemens Sentron panelboards including S4, S5, and SPP types, as well as SB1, SB2, and SB3 switchboards and Siemens Motor Control Centers.
What wire sizes are accepted by the standard lugs on this breaker?
The standard mechanical lugs accept 3/0 AWG to 500 kcmil copper wire, or 4/0 AWG to 500 kcmil aluminum wire. The lugs are rated for 75 degrees Celsius conductors.
How does the SHJD6 differ from the standard SJD6 frame?
The SHJD6 is the high interrupting capacity version of the SJD frame. While a standard SJD6 breaker has lower short circuit ratings, the SHJD69300NGT provides an elevated interrupting rating of 65kAIC at 480V and 100kAIC at 240V.
