The SKPB36BD0800 is an 800A, 3-pole molded case circuit breaker from GE's Spectra RMS series. It utilizes a solid-state electronic trip unit for precise industrial power protection. Designed for unit mounting, it installs into GE Spectra switchboards and panelboards. For modern upgrades, it is replaced by the ABB XT7LU380EGFF000XXX using a retrofit kit.
What enclosures or equipment are compatible with the SKPB36BD0800?
This SK frame breaker is designed for use in GE Spectra Series switchboards, panelboards, and motor control centers.
What functions are included in the LSIGT electronic trip unit?
The LSIGT designation indicates adjustable protection for Long-Time, Short-Time, Instantaneous, and Ground Fault. The T stands for Targets, which are visual indicators on the trip unit that display the specific type of fault that caused the breaker to trip.
Is a rating plug required to operate the SKPB36BD0800?
Yes, GE Spectra RMS breakers with solid-state electronic trip units require a rating plug to establish the continuous current rating. For this 800A SK frame, an SRPK800A series rating plug is required and is typically sourced separately.
Which lug kit is recommended for terminating conductors on this 800A breaker?
The GE TCAL81 lug terminal kit is commonly used for SK800 and SK1200 frames. It accommodates three 3/0 AWG to 500 kcmil copper or aluminum conductors per phase.
Has the GE SKPB36BD0800 been discontinued?
Yes, following ABB acquiring GE Industrial Solutions, the Spectra RMS breaker line was phased out. ABB now offers Tmax XT series breakers and direct retrofit kits to replace legacy SK frame breakers in existing GE switchboards and panelboards.
