Product FAQs
9 answersWhich panelboards and switchboards are compatible with the SGHB36BC0400?
This SG-frame breaker is specifically designed for GE Spectra Series panelboards, switchboards, and motor control centers. It will not fit standard GE A-Series or ReliaGear panels without specific retrofit hardware.
Do I need a rating plug to operate the SGHB36BC0400?
Yes, all GE Spectra RMS circuit breakers require a front-mounted rating plug to establish the breaker's ampere rating. You must install a compatible SG-frame rating plug before energizing the breaker.
What does the LIG trip function code mean on this Spectra RMS breaker?
The LIG designation indicates the electronic trip unit provides adjustable Long-Time (overload), Instantaneous (short-circuit), and Ground-Fault protection. This allows precise time-current coordination with other breakers in your electrical system.
What type of electronic trip unit is installed on the SGHB36BC0400?
This breaker is equipped with a digital, solid-state MicroVersaTrip Plus electronic trip unit. It features an LCD and keypad for viewing and adjusting the LIG protective function settings to match your system coordination study.
Will I receive an ABB or GE branded breaker when ordering the SGHB36BC0400?
Because ABB acquired GE Industrial Solutions, this exact Spectra RMS breaker may arrive with either ABB or GE branding. The physical dimensions, mounting, and internal components are identical regardless of the label.
Is the SGHB36BC0400 suitable for reverse-feed applications?
Yes, GE Spectra RMS SG-frame circuit breakers feature a solid-state trip system and internal accessory design that allows them to be safely reverse fed.
How does the true RMS sensing benefit my electrical system?
The digital true RMS sensing accurately monitors current for both standard sinusoidal and non-sinusoidal loads. This prevents nuisance tripping caused by harmonics from equipment like variable frequency drives, welders, and computer power supplies.
What is the modern replacement for the SGHB36BC0400 if I am upgrading my panel?
The GE Spectra series is a legacy product line. For new installations or complete upgrades, ABB has replaced the SG frame with the Tmax XT5 series. Upgrading an existing Spectra panel to the XT5 requires specific ABB retrofit kits.
Can I install internal accessories like a shunt trip or auxiliary switch in the field?
Yes, the Spectra RMS SG frame accepts a full range of internal accessories, including shunt trips, undervoltage releases, and bell alarms. These are UL listed for field installation and drop into the front of the breaker without removing the main cover.
