ABB / General Electric SGLL36AT0600 Molded Case Circuit Breaker

Yes, this Spectra RMS circuit breaker requires a field-installable rating plug to establish the long-time trip point. For a maximum 600A continuous rating, you must install the SRPG600A600 plug. Other SRPG series plugs can be used to safely lower the breaker rating for smaller loads.

The standard 3-pole mechanical lug kit for this SG frame breaker is the TCLK365. It provides a wire range of two 2/0 AWG to 500 kcmil cables or one 8 AWG to 600 kcmil cable per phase, and accepts both copper and aluminum conductors.

LSI indicates that the solid-state electronic trip unit includes adjustable Long-Time, Short-Time, and Instantaneous trip functions. This allows panel builders to precisely coordinate the breaker's trip curve with upstream and downstream protective devices in the electrical distribution system.

This unit mount molded case circuit breaker is designed specifically for use in General Electric Spectra Series panelboards, switchboards, and motor control centers. It serves as a direct replacement for existing SG-frame breakers in these GE enclosures.

Yes, the GE SG600 frame design provides current-limiting protection. This actively limits the peak let-through current during a fault, minimizing electrical and mechanical stress on downstream components and improving overall system safety.

Yes, Spectra RMS breakers are designed to accept field-installable internal accessories, such as shunt trips, undervoltage releases, and bell alarms. These modular accessories can be dropped into the accessory pockets without requiring breaker disassembly.

Yes, the solid-state trip system uses digital sampling to determine the true RMS value of both sinusoidal and non-sinusoidal currents. This prevents nuisance tripping in systems with high harmonic loads, such as those powering variable frequency drives or extensive computer networks.
