Product FAQs
8 answers
What types of equipment is the SKLL3608L4XX compatible with?
This bolt-on circuit breaker is designed for use in GE and ABB Spectra Series Switchboards, Spectra Series Power Panelboards, and Motor Control Centers.
Does the SKLL3608L4XX require a rating plug to operate?
Yes, Spectra RMS breakers utilize interchangeable front-mounted rating plugs, such as the SRPK series, to establish or change the continuous ampere rating of the breaker.
What adjustments can be made with the LSIG trip unit on this breaker?
The solid-state electronic trip unit allows you to adjust Long-Time, Short-Time, Instantaneous, and Ground-Fault settings. This provides precise selective coordination and overcurrent protection for complex electrical systems.
Why is this breaker listed under both ABB and General Electric?
ABB acquired GE Industrial Solutions, meaning Spectra RMS series breakers like the SKLL3608L4XX may feature either GE or ABB branding depending on the manufacturing date. They are physically and electrically identical.
Does the ground fault protection on the SKLL3608L4XX serve as personnel protection?
No, the ground fault function in an LSIG trip unit provides equipment ground fault protection to prevent arcing and machinery damage. It is not designed for personnel ground fault circuit interruption.
How does the solid-state trip unit handle non-linear loads?
The Spectra RMS trip system uses true RMS current sensing technology. This allows the breaker to accurately monitor and respond to overcurrent conditions from non-sinusoidal loads, such as variable frequency drives and computers, without nuisance tripping.
Can the SKLL3608L4XX be reverse fed?
Yes, GE Spectra RMS circuit breakers are UL Listed for reverse feed applications, allowing flexibility during installation in panelboards and switchboards.
What frame size does the SKLL3608L4XX belong to?
This breaker is part of the SK1200 frame size within the Spectra RMS family. While the frame can handle up to 1200 amps, this specific model is configured with an 800-amp sensor.
