Product FAQs
5 answersWhy might my SKLC3612L7XX breaker arrive with ABB branding instead of GE?
ABB acquired GE Industrial Solutions in 2018. As a result, Spectra RMS breakers like the SKLC3612L7XX may feature either ABB or GE branding depending on the manufacturing date. Both versions are identical in form, fit, and function.
Does the SKLC3612L7XX require a rating plug to operate?
Yes, all GE Spectra RMS circuit breakers require a rating plug to establish the continuous ampere rating. For this 1200A SK frame breaker, you will need an SRPK1200A series rating plug, such as the SRPK1200A1200. The rating plug installs directly into the front of the trip unit.
What does the L7XX in the SKLC3612L7XX catalog number indicate?
The L7XX suffix designates that the breaker is equipped with a microEntelliGuard electronic trip unit featuring LSI-CP functions. This provides adjustable Long-Time, Short-Time, and Instantaneous protection, along with Control Power capabilities for advanced metering.
What is the modern replacement for the legacy SKLC3612L7XX breaker?
For new installations or complete panel upgrades, the ABB Tmax XT7 series serves as the modern equivalent to the legacy GE Spectra SK frame. Upgrading an existing Spectra panelboard to the XT7 requires a specific ABB retrofit kit.
Can the SKLC3612L7XX be reverse fed?
Yes, GE Spectra RMS SK1200 line breakers, including the SKLC3612L7XX, are suitable for reverse feed applications per UL File E11592.
