Product FAQs
6 answersCan the SKLC3612L4XX be reverse fed?
Yes, this molded case circuit breaker is suitable for reverse fed applications, allowing power to be supplied to the bottom terminals instead of the top without affecting the trip unit performance.
What size wire do the lugs on this 1200A breaker accept?
The terminal lugs are designed to accept four conductors per phase. They accommodate copper or aluminum wire ranging from 250 kcmil to 500 kcmil.
How does the microEntelliGuard LSIG trip unit function?
The LSIG electronic trip unit provides fully adjustable Long-Time, Short-Time, Instantaneous, and Ground-Fault protection. This allows panel builders to precisely coordinate the breaker with other protective devices in complex electrical distribution systems.
Does this breaker support facility power monitoring?
Yes, the integrated microEntelliGuard trip unit features basic metering communication capabilities, allowing for integration with building management or power monitoring networks.
Which enclosures and boards accept this SK frame breaker?
This bolt-on breaker is specifically designed for direct installation into GE Spectra Series Panelboards, GE Spectra Series Switchboards, and GE Motor Control Centers.
Why is this breaker listed as ABB / General Electric?
ABB acquired GE Industrial Solutions. As a result, Spectra Series components like this SKLC frame may feature either GE or ABB labels, but they are exact drop-in replacements with identical fit and function.
