Description
Built for heavy-duty commercial environments, this 600A electronic trip breaker offers reliable current-limiting performance. The microprocessor-based unit ensures accurate overcurrent detection. Designed for bolt-on installation, it fits Spectra Series panelboards and motor control centers. When replacing legacy components, the ABB XT5H 600 serves as the modern substitute via a retrofit kit. Adjustable LSI parameters allow for superior system coordination alongside a 65kAIC rating at 480V.Specifications

Product FAQs
6 answersCan the SGLA36AT6600C be used in reverse feed applications?
Yes, GE Spectra RMS circuit breakers are suitable for reverse feed. They do not have line or load markings, allowing incoming power cables or busbars to be connected to either the upper or lower terminals as required by the application.
Is the SGLA36AT6600C manufactured by GE or ABB?
This breaker was originally manufactured by General Electric. Following ABB's acquisition of GE Industrial Solutions, it may carry either the GE or ABB brand label depending on the production date. The physical breaker and specifications remain identical regardless of the label.
What is the modern replacement for the legacy GE SGLA36AT6600C?
The GE Spectra RMS series is a legacy product line. Facilities looking to upgrade or replace this breaker typically use the ABB Tmax XT5 series, which can be installed into existing Spectra panelboards and switchboards using a specialized retrofit kit.
What does the LSI trip function on this breaker indicate?
The solid-state electronic trip unit features LSI functions, meaning it provides adjustable Long-Time (overload), Short-Time (short circuit), and Instantaneous (high-level short circuit) protection. This allows for precise coordination in complex electrical systems.
Does the SGLA36AT6600C provide true RMS sensing?
Yes, the solid-state electronic trip unit utilizes true RMS sensing. This allows the breaker to accurately respond to high harmonic content current waveforms produced by equipment like SCR drives, welders, and computer power supplies without nuisance tripping.
Are the terminal lugs field-replaceable on the SGLA36AT6600C?
Yes, the terminal lugs on Spectra RMS SG-frame breakers can be removed or replaced in the field. When installing aluminum wire, ensure a manufacturer-recommended joint compound is applied before torquing the lugs.
