Description
Built for commercial and industrial applications, this 400A two-pole breaker features a solid-state trip unit with digital RMS sensing. It mounts into GE Spectra Series panelboards, switchboards, and motor control centers, and is replaced by the ABB XT5N 400A using the outer poles and a retrofit kit. The unit delivers precise long-time, short-time, and instantaneous (LSI) protection, along with reverse feed capability and a 100 percent continuous current rating.Specifications

Product FAQs
7 answersWhat enclosures are compatible with the SGHH26AT0400 breaker?
This breaker is designed for installation in GE Spectra Series panelboards, switchboards, and motor control centers.
Does the SGHH26AT0400 require a rating plug?
Yes, GE Spectra RMS breakers require a rating plug to establish the maximum continuous current rating. You will need an SG-frame rating plug, such as the SRPG400A400, to operate this breaker.
Can I change the amperage rating of this breaker?
Yes. Because it features an interchangeable rating plug, you can install a lower-amperage SG-frame rating plug (such as 200A or 250A) to protect smaller conductors without replacing the entire breaker frame.
What adjustments are available on the LSI trip unit?
The solid-state electronic trip unit features adjustable Long-Time, Short-Time, and Instantaneous (LSI) settings. This allows panel builders to precisely coordinate the breaker with other protective devices in the system.
What are the wire size limits for the standard lugs on this breaker?
The standard lugs can accommodate either a single conductor ranging from 8 AWG to 600 kcmil, or dual conductors ranging from 2/0 AWG to 500 kcmil.
Why is this breaker branded as both ABB and General Electric?
ABB acquired GE Industrial Solutions. Spectra RMS breakers are now manufactured under the ABB brand but retain the exact same physical and electrical specifications for direct replacement in existing GE systems.
Does the electronic trip unit require external control power?
No, the solid-state trip unit is self-powered by the internal current sensors during normal operation. External power is not required for standard overcurrent protection.
