Product FAQs
6 answersWhat equipment is the SGPB36BB0400 designed to be installed in?
This SG frame breaker is designed for use in GE Spectra Series panelboards and switchboards. It utilizes a bolt-on connection for unit mount applications.
What are the accepted wire sizes for the lugs on this 400A breaker?
The terminals accept either one wire ranging from 8 AWG to 600 kcmil or two wires ranging from 2/0 AWG to 500 kcmil. Both copper and aluminum conductors are supported.
What adjustments are available on the electronic trip unit of the SGPB36BB0400?
This breaker features an LSIT solid state trip unit, allowing adjustments for Long-Time, Short-Time, and Instantaneous pickup and delay settings. It also includes trip targets to help identify the cause of a fault.
How does the Spectra RMS trip unit measure current?
The solid state trip system uses digital sampling to determine the true RMS value of both sinusoidal and non-sinusoidal currents. This provides accurate protection even in environments with high harmonic distortion.
Does the SGPB36BB0400 require a rating plug to operate?
Yes, GE Spectra RMS breakers utilize interchangeable rating plugs to establish the continuous current rating. An SRPG series rating plug matching the desired amperage (up to the 400A frame maximum) must be installed in the front of the trip unit.
Why is this breaker listed under both ABB and General Electric?
ABB acquired GE Industrial Solutions in 2018. The Spectra RMS series, including the SG frame, was originally manufactured by General Electric and is now supported under the ABB brand portfolio.
