Product FAQs
6 answersWhat does the LIG designation on the SKLB36BC1200 trip unit mean?
It indicates the electronic trip unit provides adjustable Long-time overload, Instantaneous short-circuit, and Ground-fault protection. The included ground-fault sensing is essential for commercial equipment protection and is often required by electrical code on main services rated 1000A or higher.
Can incoming power be connected to the bottom terminals of the SKLB36BC1200?
Yes, this Spectra RMS series breaker is fully suitable for reverse fed applications, allowing you to supply incoming line power to either the top or bottom lugs safely.
Can I install this breaker in standard GE load centers?
No, the 1200A SK frame is physically too large for standard residential or light commercial load centers. It is specifically engineered to mount in heavy-duty GE Spectra Series Switchboards, A-Series Panelboards, and compatible Motor Control Centers.
Does this electronic breaker require a separate rating plug to operate?
Yes, all GE Spectra SK frame electronic breakers require an interchangeable rating plug to set the active continuous amp rating. To operate this specific breaker at its full 1200A capacity, you will need the matching SRPK1200A1200 rating plug installed.
Are field accessories supported on the SKLB36BC1200?
Yes, the SK frame supports various field-installable internal accessories, including shunt trips, auxiliary switches, and undervoltage releases. These are designed to drop in behind the front accessory cover without breaking the factory mechanism seal.
Why is this Spectra breaker branded as both ABB and General Electric?
The Spectra RMS line was originally developed by General Electric. After ABB acquired GE Industrial Solutions, they maintained production and support for this legacy architecture, so the components are now distributed and listed under the combined ABB / General Electric brand.
