Product FAQs
5 answersWhich panelboards and switchboards are compatible with the SKLC3608L3XX?
This SK-frame breaker is designed specifically for use in GE Spectra Series panelboards, Spectra Series switchboards, and GE Motor Control Centers. It secures to the bus via a standard bolt-on connection.
What adjustments are available on the microEntelliGuard trip unit?
The SKLC3608L3XX features an electronic LSI trip unit, allowing electricians to adjust the Long-Time, Short-Time, and Instantaneous pickup and delay settings. This facilitates precise selective coordination in complex distribution systems. The unit also includes basic metering and communication capabilities.
What wire sizes are accepted by the standard lugs on this 800A breaker?
The factory lugs accept three conductors per phase, ranging from 3/0 AWG to 500 kcmil. They are rated for both aluminum and copper wire. Always verify the specific torque requirements printed on the breaker faceplate during installation.
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 SKLC3608L3XX may feature either GE or ABB branding depending on the manufacturing date. Regardless of the label, they are physically and electrically identical and fully interchangeable.
What precautions are required when adjusting the LSI settings on the trip unit?
Adjustments should only be made by qualified personnel following a facility coordination study. Altering the Long-Time, Short-Time, or Instantaneous settings on an active 800A circuit can cause unintended tripping or compromise established arc flash boundaries.
