ABB / General Electric SGLC3606L3XX Molded Case Circuit Breaker

This SG-frame circuit breaker is designed to install directly into GE Spectra Series panelboards, switchboards, and motor control centers.

Yes. As a GE Spectra RMS SG-frame circuit breaker, it requires a field-installable rating plug, such as the SRPG series, to establish or adjust the maximum continuous ampere rating.

The solid-state trip unit provides adjustable Long-Time (L) for overload protection, Short-Time (S) for tracking short-circuit faults, and Instantaneous (I) for immediate high-level fault clearing. This true RMS sensing provides precise coordination advantages over standard thermal-magnetic breakers.

This breaker utilizes TCLK-series lug kits, such as the 3-pole TCLK365. The standard lugs accommodate (2) 2/0 AWG to 500 kcmil copper or aluminum conductors.

Following ABB's acquisition of GE Industrial Solutions, this breaker may feature either GE or ABB labeling. Both versions are manufactured to the identical form, fit, function, and UL standards.

For new infrastructure or complete modernization, ABB officially replaces the legacy Spectra RMS SG-frame breakers with the Tmax XT5 series. However, the SGLC3606L3XX remains available for direct maintenance replacements in existing Spectra panels.

Yes, this solid-state molded case circuit breaker is reverse-feed capable. It allows licensed electricians to wire the power supply to either the top or bottom terminals depending on the panel configuration.

Yes. While the frame has a maximum capacity of 600A, you can swap the front-mounted SRPG rating plug, like the SRPG600A400 or SRPG600A500, to lower the maximum continuous ampere rating to meet your specific load requirements.

This interrupting rating indicates the breaker can safely clear a maximum fault current of 65,000 amps at 480VAC. The SGLC3606L3XX is also rated for 100kAIC at 240VAC and 65kAIC at 600VAC, providing robust protection for commercial and industrial loads.

It is a unit-mount, bolt-on circuit breaker. It bolts directly to the internal bus architecture of Spectra Series enclosures, offering a highly secure connection for heavy electrical loads.
