Description
Built for commercial applications, the GE SGLA26AT0400 is a 2-pole, 400A molded case circuit breaker. This bolt-on MCCB mounts into GE Spectra Series panelboards, switchboards, and motor control centers. For modern upgrades, it can be replaced by the ABB XT5H series using a Spectra retrofit kit. Featuring a solid-state electronic trip unit, it provides adjustable long-time, short-time, and instantaneous (LSI) functions. It boasts a 65kAIC rating at 480VAC and includes true RMS sensing.Specifications

Product FAQs
7 answersWhat panelboards and equipment are compatible with the SGLA26AT0400?
This breaker is designed for use in GE Spectra Series Panelboards, Switchboards, and Motor Control Centers.
What frame size is the SGLA26AT0400?
This breaker belongs to the SG frame group within the Spectra RMS family. The SG frame supports a maximum rating of 600A, though this specific model is equipped with a 400A sensor.
Is the SGLA26AT0400 suitable for reverse feeding?
Yes, Spectra RMS circuit breakers are suitable for reverse feed applications and do not have specific line or load markings.
Does the SGLA26AT0400 require a rating plug to operate?
Yes, this Spectra RMS breaker requires a front-mounted, field-installable interchangeable rating plug, such as the SRPG series. The installed plug establishes the continuous ampere rating, which must be equal to or less than the 400A sensor rating.
What adjustments can be made with the LSI trip unit on this breaker?
The solid-state electronic trip unit allows you to adjust the Long-Time, Short-Time, and Instantaneous trip functions to coordinate with other protective devices in your electrical system.
What does the RMS sensing feature do on the SGLA26AT0400?
The digital solid-state trip system uses digital sampling to accurately determine the true RMS value of both sinusoidal and non-sinusoidal currents, providing reliable protection even in environments with harmonic distortion.
Is this breaker manufactured by GE or ABB?
GE Industrial Solutions was acquired by ABB. As a result, the SGLA26AT0400 may be branded as either General Electric or ABB depending on the manufacturing date, but the physical dimensions and performance remain identical.
