ABB / General Electric SGLB36BD0600 Molded Case Circuit Breaker

The 'T' indicates the trip unit features built-in trip targets, or fault indicators. These targets display exactly which type of fault, such as an overload, short circuit, or ground fault, caused the breaker to trip, which significantly speeds up troubleshooting.

This 600A SG-frame requires an interchangeable rating plug from the GE SRPG series, such as the SRPG600B600, to establish its maximum continuous ampere rating and long-time trip point.

The standard mechanical lug kit for a 3-pole 600A SG-frame breaker is the TCLK365. This kit accepts either one 8 AWG to 600 kcmil conductor, or two 2/0 AWG to 500 kcmil conductors per phase, accommodating both copper and aluminum wiring.

Yes. The onboard trip unit features fully adjustable Long-Time, Short-Time, Instantaneous, and Ground-Fault parameters. This allows for precise coordination with other protective devices within your electrical distribution system.

Yes. GE Spectra RMS SG-frame circuit breakers are UL listed for reverse-feed applications. This allows you to supply power from either the top or bottom terminals, offering greater flexibility when wiring panelboards and switchboards.

Following ABB's acquisition of GE Industrial Solutions, the Spectra RMS line became obsolete. For modernization projects, ABB recommends transitioning to the Tmax XT5 molded case circuit breaker using an approved retrofit kit.

Yes. The SGLB frame utilizes current-limiting technology to quickly isolate faults. This significantly reduces the peak let-through current, which limits electrical and mechanical stress on downstream equipment during short-circuit events.
