Description
Part of the Spectra RMS family, this 400A molded case circuit breaker utilizes microprocessor-based sensing for precise coordination. The unit mounts into GE power panelboards and switchboards, offering robust performance for industrial applications. Note that this legacy SG frame is replaced by the Tmax XT5 series, which requires a retrofit kit for installation in existing enclosures. Featuring a 65kAIC rating at 480VAC, it includes adjustable long-time and instantaneous trip functions.Specifications

Product FAQs
6 answersWhat equipment is the SGLB36BA0400 designed to fit?
This SG frame molded case circuit breaker is engineered specifically for installation in GE Spectra Series Switchboards and Power Panelboards.
Do I need a separate rating plug to operate this breaker?
Yes, all GE Spectra RMS breakers require an interchangeable rating plug to establish the continuous current rating. For this 400A SG frame, you will need a compatible SRPG400A series rating plug to match your specific load requirements.
Can I change the continuous amperage of this breaker without replacing the entire unit?
Yes. Because the SGLB36BA0400 uses interchangeable rating plugs, you can lower the continuous current rating below the 400A maximum frame size simply by installing a lower-rated SRPG400A series plug, such as a 250A or 300A version.
How does the electronic trip unit differ from a standard thermal-magnetic breaker?
The SGLB36BA0400 features a solid-state electronic trip unit with LI (Long-Time and Instantaneous) functions. Unlike fixed thermal-magnetic breakers, this allows an electrician to precisely adjust the trip curve settings to coordinate with other protective devices in your system.
Does the SGLB36BA0400 provide equipment ground fault protection?
No. The LI trip function on this breaker provides Long-Time and Instantaneous protection only. It does not include the Ground Fault (G) function. If your application requires equipment ground fault protection, you will need a breaker equipped with an LSIG or LIG trip unit.
Is there a difference between the ABB and General Electric versions of the SGLB36BA0400?
No. Following ABB's acquisition of GE Industrial Solutions, Spectra RMS breakers are manufactured under both brand names. An ABB branded SGLB36BA0400 is an exact drop-in replacement for a GE branded unit, sharing the same physical dimensions and electrical characteristics.
