Product FAQs
8 answersDoes the SGHC3604L7XX require a rating plug to operate?
Yes, this Spectra RMS SG-frame breaker requires an interchangeable rating plug, such as the SRPG400A series, to establish its continuous ampere rating. The rating plug must be installed for the breaker to function properly and protect the connected cable.
What wire sizes do the standard lugs on the SGHC3604L7XX accept?
When equipped with standard TCLK365 or TCOK365 mechanical lugs, this 400A SG-frame breaker accepts copper or aluminum wire ranging from 2/0 AWG to 600 kcmil. Always verify the specific lug catalog number installed on your breaker for exact wire range and torque specifications.
What does the L7XX in the SGHC3604L7XX catalog number indicate?
The L7 designates an electronic trip unit with Long-Time, Short-Time, and Instantaneous (LSI) protection, plus Control Power (CP). The XX indicates that no additional advanced protection functions, such as ground fault or neutral protection, are included.
Which panelboards are compatible with the SGHC3604L7XX breaker?
This bolt-on molded case circuit breaker is designed for use in GE Spectra Series panelboards, switchboards, and motor control centers. It is not compatible with standard GE A-Series or ReliaGear lighting panels.
Can the SGHC3604L7XX be reverse fed?
Yes, GE Spectra RMS circuit breakers with electronic trip units are UL Listed for reverse feed applications, allowing them to be used as main breakers or in back-fed configurations.
What is the current replacement for the legacy SGHC3604L7XX?
The GE Spectra RMS series is a legacy product line. ABB currently replaces 400A SG-frame breakers with the Tmax XT5 series, such as the XT5NU340AFFF000XXX, when used with the appropriate retrofit kit for existing Spectra panelboards.
How is the continuous current rating adjusted on this breaker?
The continuous current rating is not adjusted via dials on the trip unit. Instead, it is established by installing a specific UL Listed interchangeable rating plug matching the required ampacity of the circuit, up to the 400A maximum frame size.
Does this breaker include ground fault protection?
No, the SGHC3604L7XX features an LSI-CP trip unit (Long-Time, Short-Time, Instantaneous, and Control Power). It does not include ground fault trip or ground fault alarm functions.
