Product FAQs

6 answers
Does the SGHH36AT0400 require a rating plug to operate?

Yes, this Spectra RMS circuit breaker requires a front-mounted rating plug, such as the SRPG400A400, to establish the continuous ampere rating. The rating plug must be installed for the breaker to function properly.

What are the wire size requirements for the SGHH36AT0400 lugs?

The standard lugs accept either one wire ranging from 8 AWG to 600 kcmil, or two wires ranging from 2/0 AWG to 500 kcmil. Ensure the cable size matches the ampere rating established by the installed rating plug.

What trip functions are adjustable on the SGHH36AT0400?

This breaker features a solid-state electronic trip unit with LSI functions. It includes an adjustable instantaneous trip and tracking short-time protection, while the long-time trip point is established by the interchangeable rating plug.

What does the SGHH frame designation indicate?

In the GE Spectra RMS series, the SG frame designates a 400A or 600A maximum frame size. The HH in SGHH indicates the specific interrupting capacity tier, which provides 35kAIC at 480VAC and 65kAIC at 240VAC.

What equipment is the SGHH36AT0400 designed to be installed in?

This bolt-on SG frame breaker is engineered for use in GE Spectra Series panelboards, switchboards, and motor control centers.

Is the GE SGHH36AT0400 still actively manufactured?

The Spectra RMS series is a legacy General Electric product line. ABB acquired GE Industrial Solutions and now offers the Tmax XT series, such as the XT5N, as a modern replacement which can be installed using a retrofit kit.
