ABB / General Electric SGLL36AT0400 Molded Case Circuit Breaker

When upgrading to newer platforms, this breaker is replaced by the ABB Tmax XT5 series, specifically catalog number XT5HU340BFFF000XXX. An ABB retrofit kit is required to install the replacement breaker in existing GE Spectra Series equipment.

Yes, this Spectra RMS breaker requires a front-mounted, interchangeable rating plug from the SRPG family to establish the continuous ampere rating and long-time trip point. The breaker will not function properly without the correct rating plug installed.

The TCLK365 Spectra lug kit is compatible with this SG600 frame breaker. The kit includes three lugs and a protective cover, accommodating wire sizes up to 600 kcmil for copper or aluminum conductors.

The breaker is equipped with a solid-state electronic trip unit featuring true RMS sensing. It provides adjustable LSI (Long-Time, Short-Time, and Instantaneous) protection, using digital sampling to accurately monitor both sinusoidal and non-sinusoidal currents.

Yes, this circuit breaker is 100 percent rated. When installed in an appropriately sized and ventilated enclosure, it can carry its full 400A continuous current rating without being limited to the standard 80 percent derating factor.

Yes, this Spectra RMS circuit breaker is suitable for reverse-feed applications. Power can be supplied to either the line or load terminals without compromising the electronic trip unit or interrupting capabilities.

This unit-mount circuit breaker is specifically designed for installation in GE Spectra Series panelboards, switchboards, and motor control centers.

Yes, this breaker features current-limiting capabilities. It is designed to quickly interrupt high fault currents, reducing let-through energy and minimizing potential thermal and magnetic damage to downstream electrical equipment.
