Description
A premium solution for commercial facilities, the GE SFPA36AT2250C is a 3-pole, 250A molded case circuit breaker from the Spectra RMS family. Its 100% continuous rating ensures it can handle full-capacity loads without the standard 80% derating requirement. This SF-frame MCCB is built to bolt into GE Spectra series panelboards and motor control centers. For future upgrades, it crosses to the XT4LU3250BFF000XXX with an adapter kit. It features true RMS sensing and adjustable LSI trip settings.Specifications

Product FAQs
9 answersWhat panelboards are compatible with the SFPA36AT2250C?
This bolt-on circuit breaker is designed for installation in GE Spectra Series panelboards, switchboards, and motor control centers.
Does the SFPA36AT2250C require a separate rating plug?
Yes, the GE Spectra RMS SF250 frame requires a front-mounted interchangeable rating plug, such as the SRPF250A250, to establish the continuous ampere rating.
What wire sizes do the standard lugs on this SF-frame breaker accept?
Standard lugs for the GE SF250 frame accept 8 AWG to 350 kcmil copper or aluminum wire.
What is the standard lug kit part number for this breaker?
The standard lug kit for the GE Spectra RMS SF250 frame is the TCAL29, which accommodates 8 AWG to 350 kcmil wire.
What does the LSI designation mean on this electronic trip unit?
LSI indicates the breaker features adjustable Long-Time, Short-Time, and Instantaneous trip functions. The tracking short-time function allows for precise coordination with downstream devices like fuses or starter overloads.
What is the modern replacement for the legacy SFPA36AT2250C?
ABB has replaced the legacy GE Spectra RMS SF frame with the Tmax XT4 series. Upgrading to the XT4LU3250BFF000XXX requires a specific retrofit adapter kit to fit existing Spectra panelboards.
Can the SFPA36AT2250C be reverse fed?
Yes, GE Spectra RMS circuit breakers with electronic trip units are suitable for reverse feed applications because they do not have line and load markings.
Are the lugs on the SF frame field-installable?
Yes, the SF frame features snap-in lugs that can be installed in the field without requiring disassembly or removal of the breaker cover.
How does the electronic trip unit handle harmonic currents?
The digital solid-state trip system features true RMS sensing, providing an accurate response to high harmonic content waveforms produced by variable frequency drives and computer power supplies without nuisance tripping.
