Integrating true RMS sensing technology, this 200A Sentron JD-frame breaker offers precise LSI (Long-Time, Short-Time, Instantaneous) electronic trip protection. It installs into Siemens S4, S5, and SPP panelboards, as well as SB-series switchboards and motor control centers. While this specific unit is often replaced by the Sensitrip IV or newer 3VA series, it remains a critical component for maintaining existing infrastructure, delivering a high interrupting capacity of 65kAIC at 480VAC.

Product FAQs
5 answers
Which Siemens panelboards and switchboards accept the SHJD69200NT breaker?
This JD-frame breaker is designed for installation in Siemens Sentron panelboards (including S4, S5, and SPP models), as well as SB1, SB2, and SB3 switchboards and motor control centers.
How does the SHJD69200NT mount inside an electrical enclosure?
This is a unit-mount, bolt-on circuit breaker. It requires specific Siemens mounting hardware kits or strap kits to properly attach to the busbars in Sentron panelboards or switchboards.
What does the "NT" suffix indicate in the SHJD69200NT catalog number?
The "NT" suffix designates that this breaker is equipped with an LSI (Long-Time, Short-Time, Instantaneous) electronic trip unit. It does not include ground fault protection. Breakers requiring integrated ground fault protection will feature an "NGT" (LSIG) suffix instead.
What does the "H" in the SHJD69200NT part number represent?
The "H" indicates that this is a high-interrupting circuit breaker. It provides a higher short-circuit interrupting rating (65kAIC at 480V) compared to standard SJD6 models, which are typically rated for 35kAIC at 480V.
Can the SHJD69200NT replace older thermal-magnetic JD-frame breakers?
Yes, this electronic trip breaker shares the same physical footprint and mounting hardware requirements as standard thermal-magnetic JD-frame breakers, making it a direct drop-in upgrade for compatible Siemens and ITE enclosures.
