Product FAQs
10 answersIs the GE Spectra SGPA36AT4400C still in active production?
No. The GE Spectra RMS series has been retired following ABB's acquisition of GE Industrial Solutions. It is officially replaced by the ABB Tmax XT series, specifically the XT5 frame, which requires a retrofit kit for installation into legacy Spectra panelboards.
Does this breaker require a separate rating plug?
Yes. Like all GE Spectra RMS breakers, the SGPA36AT4400C requires a front-mounted rating plug (SRPG series) to establish the specific operational amperage, even if you intend to use it at the maximum 400A frame rating.
What does the C suffix in the SGPA36AT4400C catalog number indicate?
The C at the end of the catalog number indicates that the breaker comes with standard factory-installed line and load lugs.
What adjustments does the LSI electronic trip unit provide?
The solid-state LSI trip unit allows precise coordination by letting you adjust the Long-Time (overload), Short-Time (short circuit with intentional delay), and Instantaneous (immediate short circuit) trip functions.
Which panelboards are compatible with the SGPA36AT4400C?
This SG-frame breaker is designed for bolt-on installation in legacy GE Spectra Series power panelboards, switchboards, and motor control centers.
Can this breaker be reverse fed?
Yes. GE Spectra RMS molded case circuit breakers do not have line and load restrictions and can be reverse fed safely.
What does the True RMS Sensing feature do on this breaker?
True RMS sensing allows the electronic trip unit to accurately measure and respond to both sinusoidal and non-sinusoidal currents, preventing nuisance tripping from harmonic loads like variable frequency drives or discharge lighting.
How is the SGPA36AT4400C mounted into the panelboard?
This is a unit-mount, bolt-on circuit breaker. It bolts directly to the busbars in compatible GE Spectra panelboards and switchboards using the appropriate mounting hardware kit.
Is this circuit breaker HACR rated?
Yes. The SGPA36AT4400C is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment.
Why choose the SGPA frame over the SGLA frame?
The SGPA frame provides a higher short-circuit interrupting capacity. It is rated for 100kAIC at 480VAC, whereas the standard SGLA frame is rated for 65kAIC at 480VAC.
