Description
Built for heavy-duty industrial environments, this 400A unit-mount MCCB utilizes advanced microprocessor-based sensing. The SG-frame component integrates seamlessly into Spectra series switchboards and motor control centers. Equipped with adjustable short-time and instantaneous functions, it ensures optimal coordination across complex electrical networks. For facility upgrades, this model is superseded by the XT5SU340AFFF000XXX, necessitating the SRFB6XT5BFPX adapter for older panels.Specifications

Product FAQs
8 answersWhat equipment is the EZSGHA36AT0400 designed to be installed in?
It is engineered specifically for use in GE Spectra Series Panelboards, Switchboards, and Motor Control Centers.
What type of wire and gauge can be used with the lugs on this breaker?
The factory-installed lugs are rated for both copper and aluminum (Cu/Al) conductors, accepting two wires per phase ranging from 2/0 AWG to 500 kcmil.
What advantages does the LSI electronic trip unit offer over standard breakers?
The Long-Time, Short-Time, and Instantaneous (LSI) functions on this solid-state trip unit allow panel builders to precisely adjust the trip curve for better selective coordination with downstream devices.
How does the bolt-on connection work for the EZSGHA36AT0400?
As a unit mount breaker, it features a bolt-on connection type that secures directly to the busbars of compatible GE enclosures, ensuring a high-capacity, low-resistance mechanical connection.
Can this breaker replace older GE Spectra RMS SG frames?
Yes, the EZSGHA36AT0400 is a direct physical replacement for other SG frame breakers in existing GE distribution equipment, provided the 400A rating and interrupting capacities meet your system requirements.
Is this SG frame breaker suitable for high-fault industrial systems?
Yes, it offers robust fault protection with interrupting ratings up to 65kA at 240VAC and 35kA at 480VAC, making it ideal for commercial and industrial facilities with high available fault currents.
Why is the trip adjustability listed as fixed thermal and adjustable magnetic?
On this specific Spectra RMS electronic trip breaker, the continuous current overload protection (thermal equivalent) is determined by a fixed rating plug, while the short-circuit and instantaneous (magnetic equivalent) pickup levels can be adjusted to match system coordination needs.
Will this breaker work in standard GE PowerMark Gold load centers?
No, the EZSGHA36AT0400 is an SG frame molded case circuit breaker designed for heavy-duty Spectra Series Panelboards and Switchboards. It will not fit in residential PowerMark Gold load centers.
