Description
Engineered for heavy-duty industrial applications, this three-pole Spectra RMS breaker provides advanced LSI electronic trip functions. Microprocessor-based sensing ensures precise coordination across complex distribution systems. Designed to bolt into GE power panels, this SK frame unit serves as a robust main or feeder. It has been superseded by the ABB Tmax XT7H series but remains essential for maintaining existing infrastructure.Specifications

Product FAQs
8 answersIs a rating plug required for the GE SKLA36AT1200?
Yes, the Spectra RMS SKLA36AT1200 requires a front-mounted, interchangeable rating plug (such as the SRPK1200A series) to establish the breaker's continuous ampere rating. The rating plug is not included with the breaker frame and must be sourced separately.
Are terminal lugs included with this SK1200 frame circuit breaker?
No, the SKLA36AT1200 is supplied as a frame only and does not include terminal lugs. You must purchase standard lugs, such as the TCAL125, or specific copper/aluminum lug kits separately depending on your conductor size and application.
Can the SKLA36AT1200 be reverse fed?
Yes. All Spectra RMS circuit breakers, including this SK frame unit, are suitable for reverse feed applications. They do not have specific line or load markings, allowing incoming power cables to be connected to either the top or bottom terminals.
How does the electronic LSI trip unit function?
The solid-state electronic trip unit allows field-adjustable settings for Long-Time, Short-Time, and Instantaneous trip thresholds to ensure precise overcurrent coordination. This flexibility is essential for isolating faults quickly without taking the entire distribution system offline.
Why is the SKLA36AT1200 listed as both ABB and General Electric?
ABB acquired GE Industrial Solutions, integrating the GE Spectra RMS line into their own electrical portfolio. Whether branded as GE or ABB, the SKLA36AT1200 breaker is physically and functionally identical and maintains the exact same UL listings.
What equipment is the SKLA36AT1200 designed to be installed in?
This bolt-on SK frame breaker is engineered for heavy industrial distribution and is primarily used as a main or feeder breaker in GE Spectra Series switchboards and standard power panels.
What mounting hardware is needed for this breaker?
As a bolt-on circuit breaker, it requires specific hardware kits, such as the AMCB3KMFP mounting kit, to properly secure the frame to the panel busbars. Mounting hardware is tied to the exact panel type and is not included with the bare breaker.
What is the advantage of the True RMS sensing on the SKLA36AT1200?
True RMS sensing allows the breaker's microprocessor to accurately calculate the heating value of distorted electrical waveforms. This is critical in modern facilities with non-linear loads like variable frequency drives and switching power supplies, preventing nuisance tripping.
