Product FAQs
8 answersIs the GE SKLC3612L5XX still actively manufactured, or has it been replaced?
This legacy GE Spectra RMS circuit breaker has been officially replaced by the ABB Tmax XT7 series. However, exact replacements are often still available for existing panelboards and switchboards.
Does the SKLC3612L5XX require a rating plug to operate?
Yes, GE Spectra SK1200 frame breakers require a front-mounted rating plug, such as the SRPK1200A1200, to establish the breaker ampere rating and enable the electronic trip unit.
What does the LSIA trip function on this breaker include?
The LSIA electronic trip unit provides adjustable Long-Time, Short-Time, and Instantaneous overcurrent protection, alongside a Ground Fault Alarm. The alarm function alerts operators to ground faults without tripping the breaker.
What equipment is the SKLC3612L5XX compatible with?
This breaker is designed for installation in GE Spectra Series Panelboards, GE Spectra Series Switchboards, and GE Motor Control Centers.
Are lugs included with the SKLC3612L5XX breaker?
Lugs are generally not included with the base breaker frame and must be ordered separately. Compatible lug kits for the SK1200 frame, such as the TCAL124 or TCAL121, accept multiple large-gauge copper or aluminum conductors per phase.
Can the SKLC3612L5XX be reverse fed?
Yes, GE Spectra RMS circuit breakers are suitable for reverse feed applications. They have no line or load markings, allowing incoming power cables or busbars to be connected to either the upper or lower terminals.
Can the trip unit settings be adjusted in the field?
Yes, the integrated microEntelliGuard electronic trip unit features an interface for viewing and changing the various protective function settings in the field to ensure proper system coordination.
What safety precautions should be taken before adjusting the trip unit settings?
Always ensure the breaker is de-energized before installing the rating plug or adjusting the trip unit settings. Incorrect settings can result in a lack of system coordination or inadequate equipment protection.
