Product FAQs
7 answersWhat equipment is compatible with the SKLL3612L3XX breaker?
This bolt-on breaker is designed for installation in GE Spectra Series switchboards, Spectra Series power panelboards, and compatible motor control centers.
Does the SKLL3612L3XX require a separate rating plug?
Yes, this Spectra RMS SK frame breaker requires a front-mounted, interchangeable rating plug, such as the SRPK1200A1200, to establish its continuous current rating. The breaker requires this plug for proper operation.
Will this breaker be branded as GE or ABB?
Because ABB acquired GE Industrial Solutions, this breaker may arrive with either ABB or GE branding depending on the production date. Both versions are identical in form, fit, and function.
What do the LSI trip functions allow me to adjust?
The LSI solid-state trip unit allows you to adjust the Long-Time, Short-Time, and Instantaneous pickup and delay settings. This provides precise selective coordination for complex industrial electrical systems.
How can I secure the SKLL3612L3XX in the OFF position for maintenance?
You can install a compatible handle padlock attachment, such as the GE SKPLD locking device, to mechanically lock the breaker off and prevent unauthorized operation during servicing.
How does the electronic trip unit detect faults?
The solid-state trip system uses digital sampling to determine the true RMS value of the current. This ensures accurate sensing and protection even when non-sinusoidal currents or harmonics are present in the system.
Can the SKLL3612L3XX be reverse fed?
Yes, this Spectra RMS electronic trip circuit breaker is suitable for reverse feed applications, meaning line power can be connected to either the top or bottom terminals.
