ABB / General Electric SGHA36AT4400C Molded Case Circuit Breaker

No, this SG-frame breaker is designed exclusively for GE Spectra Series panelboards and switchboards. It will not fit in standard A-Series panels or residential load centers.

The terminals support dual configurations. You can terminate a single copper or aluminum conductor ranging from 8 AWG to 600 kcmil, or two conductors ranging from 2/0 AWG to 500 kcmil per phase.

The solid-state LSI (Long-Time, Short-Time, Instantaneous) trip unit allows electricians to fine-tune the breaker's response curve. This adjustability ensures precise selective coordination with upstream and downstream devices in complex electrical systems.

Yes. Although it is configured with a 400A rating plug and sensors, it utilizes the physical footprint and internal components of the GE Spectra RMS SG600 frame size.

Following ABB's acquisition of GE Industrial Solutions, the legacy GE Spectra RMS product line transitioned under the ABB brand. The physical breaker and its compatibility remain identical to the original GE specifications.

No. While GE Spectra RMS frames often require a separate rating plug to set the continuous amperage, this specific catalog number includes the 400A rating plug pre-installed.

The SGHA36AT4400C features a bolt-on connection. It must be bolted directly to the busbars of a compatible Spectra Series panelboard or switchboard using the correct mounting hardware kit.

For safety and compliance with NFPA 70E, all adjustments to the LSI electronic trip unit should be made while the breaker is de-energized. Always follow proper lockout and tagout procedures before removing the panel cover.

Yes, ABB offers retrofit kits that allow you to upgrade legacy GE Spectra SG frames to the modern ABB Tmax XT5 platform without replacing the entire panelboard enclosure.
