Description
Rated 100kAIC at 480V, the GE SFPA36AT2150C is a 3-pole, 150A electronic trip circuit breaker designed for continuous heavy-duty loads. Being 100% rated allows this Spectra RMS breaker to carry its full nameplate amperage continuously without derating. It bolts seamlessly into Spectra series panelboards, switchboards, and MCCs. When replacing this unit, the XT4LU3150BFF000XXX serves as the modern substitute via a retrofit kit. The solid-state trip unit offers adjustable LSI functions.Specifications

Product FAQs
6 answersWhat panelboards and switchboards is the SFPA36AT2150C compatible with?
It is designed for installation in GE Spectra Series panelboards, switchboards, and motor control centers.
What wire size range do the standard lugs on the SFPA36AT2150C accept?
The standard lugs for the SF250 frame accept a single #8 AWG to 350 kcmil copper or aluminum wire per pole.
What rating plug is used in the SFPA36AT2150C?
This breaker utilizes the SRPF250A150 rating plug. This plug establishes the 150-amp continuous current rating on the 250-amp maximum SF250 frame.
How does the true RMS sensing in the SFPA36AT2150C handle harmonic loads?
The digital solid-state trip unit uses true RMS sensing to accurately measure both sinusoidal and non-sinusoidal currents. This prevents nuisance tripping caused by high harmonic content from equipment like variable frequency drives, welders, and computer power supplies.
What adjustability does the LSI trip unit provide on the SFPA36AT2150C?
The electronic trip unit features adjustable Long-Time, Short-Time, and Instantaneous (LSI) settings. The short-time function tracks the adjustable instantaneous setting to provide precise coordination and enhanced protection for motors and transformers.
Does installing lugs or internal accessories require disassembling the SFPA36AT2150C?
No. The GE Spectra RMS F-frame breakers feature snap-in lugs and internal accessories that can be field-installed without disassembling or removing the breaker cover.
