Product FAQs
6 answersWhich switchboards and panels are compatible with the SKLA36AT212XC?
This SK-frame breaker is designed for installation in GE and ABB Spectra Series switchboards and power panels.
What does the LSI designation indicate on this Spectra RMS breaker?
LSI indicates the electronic trip unit includes adjustable settings for Long-Time, Short-Time, and Instantaneous protection. This allows panel builders to precisely coordinate the breaker with other protective devices in the electrical system.
What are the wire size requirements for the included lugs?
The terminal lugs on this 1200A breaker accept four 250 to 500 kcmil conductors per phase. They are rated for both copper and aluminum wire.
Why is this breaker listed under both ABB and General Electric?
ABB acquired GE Industrial Solutions. The SKLA36AT212XC is the exact same Spectra RMS circuit breaker, but newer production units will feature the ABB brand name instead of the GE logo.
How is this 1200A breaker mounted into the enclosure?
The SKLA36AT212XC features a bolt-on connection type, requiring it to be securely bolted directly to the busbars of the compatible switchboard or power panel.
Can the trip settings be adjusted on the SKLA36AT212XC?
Yes, the solid state electronic trip unit is fully adjustable. Electricians can modify the LSI parameters to match the specific load requirements and fault current calculations of the facility.
