ABB / General Electric SGLC3604L7XX Molded Case Circuit Breaker

This SG-frame breaker is designed for installation in GE Spectra Series panelboards, switchboards, and motor control centers that accept unit-mount, bolt-on breakers.

The standard lugs accommodate either two 2/0 AWG to 500 kcmil conductors or a single 8 AWG to 600 kcmil conductor. The terminals are rated for both copper and aluminum wiring.

The LSI designation indicates adjustable Long-Time, Short-Time, and Instantaneous trip functions. This allows panel builders to precisely tune the overload and short-circuit response curves for selective coordination with other breakers in the electrical system.

Yes, the integrated microEntelliGuard trip unit includes basic metering communication features, allowing it to interface with compatible facility management and monitoring systems.

This is a unit-mount breaker, meaning it bolts directly to the chassis or mounting pan of the enclosure rather than plugging into a busbar.

ABB acquired GE Industrial Solutions in 2018. Depending on the manufacturing date, the SGLC3604L7XX may feature either GE or ABB branding, but the physical dimensions, SG-frame specifications, and microEntelliGuard trip units remain identical.

The microEntelliGuard electronic trip unit provides highly accurate, adjustable overcurrent protection that is not affected by ambient temperature changes. This ensures consistent trip times and better arc flash mitigation when properly coordinated.

The breaker provides a maximum interrupting capacity of 100kA at 240V AC. For higher voltage systems operating at 277V, 480V, or 600V AC, the interrupting rating is standardized at 65kA.
