Product FAQs
5 answers
Does the SKPA36AT0800 require a rating plug to operate?
Yes. All GE Spectra RMS circuit breakers require a rating plug to establish the continuous current rating. For this 800A frame, an SRPK800A series rating plug must be installed for the breaker to function properly.
Which panelboards and switchboards are compatible with the SKPA36AT0800?
This breaker is designed specifically for use in GE Spectra Series panelboards, switchboards, and motor control centers. It utilizes a bolt-on connection to secure to the bus.
How many conductors per phase do the standard lugs accept?
The standard lug configuration for this breaker accepts three conductors per phase. The terminals accommodate wire sizes ranging from 3/0 AWG to 500 kcmil for both copper and aluminum conductors.
What adjustments are available with the LSI electronic trip unit?
The LSI trip unit provides adjustable settings for Long-Time, Short-Time, and Instantaneous trip functions. This allows panel builders and electricians to fine-tune the time-current curve for optimal selective coordination with downstream and upstream protective devices.
Is the GE Spectra RMS SKPA36AT0800 still in active production?
No. The GE Spectra RMS series is a legacy product line that was phased out following the acquisition of GE Industrial Solutions by ABB. For new installations, ABB typically recommends the SACE Tmax XT series as the modern equivalent.
