Description
Engineered for commercial and industrial applications, this 400A molded case circuit breaker provides robust electronic trip protection. As a core component of the GE Spectra RMS family, it utilizes true RMS sensing for accurate current measurement. The bolt-on device installs into GE Spectra Series switchboards and power panelboards. When modernizing older infrastructure, this frame is replaced by the ABB Tmax XT5 using a dedicated retrofit kit. It delivers 65kAIC at 480VAC with LSIG functions.Specifications

Product FAQs
8 answersWhich panelboards are compatible with the SGLB36BD0400 breaker?
This SG frame breaker is designed specifically for use in GE Spectra Series switchboards and power panelboards. It requires a bolt-on connection.
What wire sizes do the lugs on the SGLB36BD0400 accept?
The standard lugs accept two 2/0 AWG to 500 kcmil aluminum conductors, or two 2/0 AWG to 400 kcmil copper conductors per phase.
What adjustability does the electronic trip unit provide on this breaker?
The SGLB36BD0400 features an LSIG solid-state trip unit. This allows electricians to adjust the long-time, short-time, instantaneous, and ground-fault pickup and delay settings to coordinate with the specific demands of the electrical system.
What is the purpose of the trip targets on this breaker?
The trip targets are visual indicators on the electronic trip unit that show which specific fault condition (long-time, short-time, instantaneous, or ground-fault) caused the breaker to trip. This aids electricians in rapid troubleshooting after a fault.
Why is this breaker listed under both ABB and General Electric?
ABB acquired GE Industrial Solutions in 2018. As a result, Spectra RMS series breakers like the SGLB36BD0400 may feature either GE or ABB branding depending on the manufacturing date, but they are physically and electrically identical.
Does the SGLB36BD0400 include integrated ground fault protection?
Yes, the G in the LSIG trip function indicates that this breaker includes built-in equipment ground fault protection, which can be adjusted via the electronic trip unit.
Can this breaker be used in a plug-in application?
No, the SGLB36BD0400 is strictly a bolt-on circuit breaker designed for hardwired connections in compatible Spectra Series enclosures.
Is the SGLB36BD0400 interchangeable with other SG frame breakers?
It can replace other 400A SG frame Spectra RMS breakers with similar interrupting ratings, provided the panelboard is configured for a 3-pole, bolt-on installation. Always verify that the required trip functions match your system coordination study before replacing a unit.
