Product FAQs
6 answersWhat equipment is compatible with the SKPC3612L3XX circuit breaker?
This 1200A Spectra RMS breaker is designed for unit-mount, bolt-on installation in GE Spectra Series switchboards, panelboards, and motor control centers.
What wire sizes are supported by the SKPC3612L3XX terminals?
The standard lug configuration accepts four 250 to 500 kcmil copper or aluminum conductors per phase. It is compatible with SK1200 frame lug kits like the TCAL124 series.
How is the continuous amperage configured on this Spectra RMS breaker?
The continuous current rating is established using a front-mounted, field-installable SRPK series rating plug. The installed rating plug must match your required ampacity and connected cable size.
What protection features are included in the LSI trip unit?
The solid-state electronic trip unit provides adjustable Long-Time, Short-Time, and Instantaneous (LSI) protection. This adjustability allows panel builders to precisely coordinate the breaker with other protective devices in the distribution system.
What is the current ABB replacement for the legacy GE SKPC3612L3XX?
Following ABB's acquisition of GE Industrial Solutions, this legacy Spectra RMS breaker is typically replaced by the ABB Tmax XT7 series, such as the XT7LU312EFFF000XXX frame. Always verify enclosure dimensions and trip unit specifications before retrofitting.
Is the SKPC3612L3XX suitable for reverse-feed applications?
Yes, GE Spectra RMS SK1200 frame circuit breakers are reverse-feed rated, allowing line power to be connected to either the top or bottom terminals.
